NAME

       config - HylaFAX configuration database

DESCRIPTION

       HylaFAX  uses  a  configuration file for the central queueing agent and
       for each facsimile modem attached to a machine.   These  files  contain
       information about the modems and about how the HylaFAX server processes
       that service these  modem  should  operate.   Configuration  files  are
       located  in  the  etc  subdirectory.   The  configuration  file for the
       faxq(8) program is named config.   The  per-modem  configuration  files
       used  by  the  faxgetty(8),  faxsend(8),  and pagesend(8) programs have
       names of the form config.devid, where devid is  an  identifier  derived
       from  the  name  of  the  modem’s  device  file;  for example ttym2 for
       /dev/ttym2, term_10 for /dev/term/10.

       Configuration files have a simple format and  are  entirely  ASCII.   A
       configuration parameter is of the form
            tag: value
       where  a  tag  identifies  a  parameter and a value is either a string,
       number, or  boolean  value.   Comments  are  introduced  by  the  ‘‘#’’
       character  and  extend  to the end of the line.  String values start at
       the first non-blank character after the ‘‘:’’ and continue to the first
       non-whitespace  character  or,  if whitespace is to be included, may be
       enclosed in quote marks (‘‘"’’).  String values enclosed in quote marks
       may  also  use  the  standard  C programming conventions for specifying
       escape codes; e.g. ‘‘\n’’ for a newline character and ‘‘\xxx’’  for  an
       octal   value.   Numeric  values  are  specified  according  to  the  C
       programming conventions (leading ‘‘0x’’  for  hex,  leading  ‘‘0’’  for
       octal,  otherwise  decimal),  except  for  a  few  parameters,  such as
       RecvFileMode, whose value is interpreted strictly as  an  octal  number
       and PageChopThreshold whose value is interpreted strictly as a floating
       point number.  Boolean values are case insensitive.  For a true  value,
       either ‘‘Yes’’ or ‘‘On’’ should be used.  For a false value, use ‘‘No’’
       or ‘‘Off’’.

       The following table itemizes the tags and the expected  type  of  their
       value.   The  first  part lists items specific to the operation of each
       server, while the second part has items related to the servicing of the
       modem.   Parameters  marked  with  a  ¹  are  used  only by the HylaFAX
       scheduler process and should appear only  in  the  file  named  config.
       Parameters  marked with a ² are used by both the scheduler and the per-
       device  applications  and  so  should   appear   in   all   appropriate
       configuration  files  (i.e.   config and any per-device files that make
       sense).  Parameters not otherwise marked should  appear  only  in  per-
       device  configuration files.  More detailed information about each item
       is given following the table.

SERVER-ORIENTED CONFIGURATION PARAMETERS

       These configuration parameters affect the general operation of the  fax
       server.

       AdaptiveAnswer
              Control  whether  or  not an adaptive answering strategy is used
              whereby an incoming call is answered in multiple ways  according
              to  the  list  specified  in  the  AnswerRotary  parameter.  For
              example, if  adaptive  answering  is  enabled  and  AnswerRotary
              specifies  ‘‘fax  data’’,  then  an  incoming call will first be
              answered as fax using ModemAnswerFaxCmd and then, if that fails,
              as  data  using  ModemAnswerDataCmd.   If  the  adaptive  answer
              strategy is not enabled,  then  calls  are  answered  using  the
              appropriate  ModemAnswer*Cmd  parameter (normally ModemAnswerCmd
              for  unattended  operation).   Note  that  the  adaptive  answer
              strategy  depends  on  many  factors  that limit its usefulness.
              When calls are answered first as fax, it  typically  only  works
              with  a  Class 1 modem because it is important that the sequence
              of operations related to answering as  fax  be  completed  in  a
              short  enough  time  that  a  subsequent answer for data be done
              before the caller times out and hangs up the telephone (for this
              reason  Class1RecvIdentTimer  should  be  set to a value that is
              shorter than FaxT1Timer.)   Also,  note  that  it  is  sometimes
              necessary  to  arrange  that the phone be placed on-hook between
              successive answers; this can typically be done by inserting  the
              appropriate  command  at  the start of the second and subsequent
              ModemAnswer*Cmds.

       AdminGroup
              Tells PAM what user group  is  allowed  to  administer  the  fax
              server.  Only useful if the server is compiled with PAM enabled.

       AnswerRotary
              The sequence of answering techniques the server should  ‘‘rotate
              through’’ when answer incoming calls.  Answering techniques are:
              Name    Description
              fax     answer a fax call
              data    answer a data call
              voice   answer a voice call
              extern  use the vgetty application to answer a call
              any     answer a call of any/unknown type
              When a call is not answered successfully,  the  server  advances
              the  rotary  to  the  next  specified  answering  technique.  If
              AdaptiveAnswer is enabled, the server will try all the answering
              techniques  for  each  incoming  call.  Otherwise, the rotary is
              advanced between unsuccessful  phone  calls.   For  example,  if
              AdaptiveAnswer  is  disabled  and  AnswerRotary is ‘‘fax data’’,
              then the calls will initially be answered as fax until the first
              call  is received that does not appear to be from a fax machine;
              after that calls will be answered as if they were  from  a  data
              modem  until  the  next unsuccessful call; after which they will
              one again be answered as fax.  Only the first  three  techniques
              listed  are  used;  any  additional ones are (silently) ignored.
              See also AnswerBias.

       AnswerBias
              The index into the AnswerRotary  list  that  the  server  should
              rotate  the  list  to after each successful incoming phone call.
              List indices are numbered starting at  zero.   For  example,  if
              AnswerRotary  is  ‘‘fax  data’’  and AnswerBias is 1, then after
              each successful inbound call, the next call will be answered  as
              data.

       AreaCode²
              The  local area code in which the facsimile modem resides.  This
              value is passed to the dial string  rules  that  are  used,  for
              example,  to  formulate canonical phone numbers for dialing (see
              DialStringRules below.)

       AuditHook¹
              Specifies  a  program  command  and  an  interest  specification
              indicating  which  events  as  described  in  faxwatch(8) should
              trigger  the  execution  of  the  program.   For  example,  this
              configuration:

                  AuditHook: "bin/hook: J*S*M*R*"

              would  cause  bin/hook  to  be  executed  upon every event.  The
              arguments passed to the hook program are  respectively  <class>,
              <mask>, <id>, and optionally [info] where...

                  <class> = JOB | SEND | MODEM | RECV
                  <mask>  = the specific event
                  <id>    = id of the job/modem with which the event is associated
                  [info]  = additional information

       BadPageHandlingMethod
              (Class 1/1.0 only) Specifies how to react to a bad page received
              from the remote sender:  one  of  ‘‘RTN’’,  ‘‘DCN’’,  or  ‘‘RTN-
              SAVE’’.

              If  a page is received in non-ECM mode with unacceptable quality
              according to PercentGoodLines or MaxConseutiveBadLines  then  it
              can  be  somewhat difficult to inform the sender of the problem.
              Historically, HylaFAX has assumed that  signalling  RTN  to  the
              sender   will   accomplish  this.   However,  some  senders  are
              incapable of retransmitting pages, and  to  reduce  burden  they
              treat an RTN signal as a receipt confirmation and proceed to the
              next page without notifying the sending user  of  the  potential
              problem  in  readability  on  the  receive-end.  (The assumption
              there being that the receiving user will notify the sending user
              if there actually is a readability problem.)

              A  setting  of ‘‘RTN’’ is the historic behavior and assumes that
              an RTN signal will be enough to get the sender to retransmit  or
              be  otherwise informed of a potential readability problem on the
              receive-end.  The previously-received page data is marked to  be
              overwritten by the next page data received from the sender.

              A  setting  of ‘‘DCN’’ tells HylaFAX to transmit a DCN signal in
              response to the post-page message  and  should  trigger  a  call
              abortion  by the sender.  This should clearly indicate a problem
              in page readability to the sender, although the receipt  of  any
              following pages in a later call cannot be guaranteed.

              A setting of ‘‘RTN-SAVE’’ more closely approximates the behavior
              of other fax receivers (especially  fax  machines).   It  causes
              HylaFAX  to  send  the  RTN  signal  but it saves the previously
              received page data and places the next transmitted page data  in
              another page.  This is the default setting.  However, this could
              result in multiple copies of the same page image being saved  in
              the  same  file  -  if  the  sender  does  indeed retransmit the
              unacceptable pages during the same call.

       BatchLogs¹
              When sending or receiving multiple documents (denoted  by  EOM),
              this  value determines if the session logs span the entire batch
              or, if set to no, only contain a single document.

       CallIDPattern
              A string that identifies  the  caller’s  identity  in  any  call
              identification messages provided by the modem (such as Caller*ID
              or DNIS/DID).  The specified  string  is  compared  against  any
              unrecognized  status  messages  received  from  the modem before
              ModemAnswerCmd is sent to the modem.  If there is a match,  then
              the  remainder  of  the  message  is returned as CallIDn where n
              corresponds to the n’th instance that this CallIDPattern is from
              the  top  in the modem configuration file.  For example, for the
              ZyXEL U-1496 this parameter would be set to
              CallIDPattern: ‘‘CALLER NAME: ’’ (note the trailing space).
              If more than one message matches  between  instances  of  "RING"
              messages, then the message remainders are concatenated.

              The   special   CallID  value  of  "SHIELDED_DTMF"  is  used  in
              conjunction  with  ModemRingResponse   and   CallIDAnswerLength.
              After executing ModemRingResponse, HylaFAX will expect DTMF data
              (usually DLE-shielded) for CallIDn until  CallIDAnswerLength  is
              reached.   Note that if the modem is in voice mode to hear these
              DTMF digits, then it  must  be  returned  to  fax  mode  in  the
              ModemAnswerCmd.   In  order  to prevent this feature from losing
              incoming fax calls, if fax sender CNG is detected while  waiting
              for  DTMF  or if ten seconds elapse without sufficient DTMF then
              the remaining expected digits will be populated  by  whitespace,
              triggering fax answering.

              For  example, the following settings will cause HylaFAX to enter
              voice mode and go off-hook when a RING  is  detected.   It  will
              then  expect four DTMF digits (presumably for routing), and then
              it will pause for 100  ms  before  returning  to  fax  mode  and
              answering the call.

                ModemRingResponse:     AT+FCLASS=8;H1
                CallIDPattern:         SHIELDED_DTMF
                CallIDAnswerLength:    4
                ModemAnswerCmd:        <delay:100>AT+FCLASS=1;A

              For  modems  that  do  not support AT+FCLASS=8 (such as some USR
              modems) this may be an appropriate equivalent:

                ModemRingResponse:      "AT#CLS=8\nAT#VLS=4\nATA"
                CallIDPattern:          SHIELDED_DTMF
                CallIDAnswerLength:     4
                ModemAnswerCmd:         "<delay:100>AT+FCLASS=1\nATA"

              Multiple entries of CallIDPattern are used together in one modem
              configuration   file   in   order  to  capture  multiple  CallID
              responses.  For example, the following  settings  would  capture
              "NDID"  responses  from  the  modem as CallID1, "NMBR" responses
              from the modem as CallID2, "NAME" responses as CallID3,  and  it
              would  trigger  ModemAnswerCmd  whenever CallID1 or CallID2 were
              longer than 7 or 10 characters, respectively.

                CallIDPattern:         "NDID="
                CallIDAnswerLength:    7
                CallIDPattern:         "NMBR="
                CallIDAnswerLength:    10
                CallIDPattern:         "NAME="

              Note that this example is only given as an example, and probably
              would  cause  unexpected results.  Because pattern-matching ends
              when ModemAnswerCmd is sent to the modem, if "NDID", "NMBR", and
              "NAME"  responses  came  from  the  modem in that order, and the
              "NDID"  response  was  at  least   7   characters   long,   then
              ModemAnswerCmd  would be sent to the modem immediately following
              the "NDID" response, and the "NMBR" and "NAME"  responses  would
              be  ignored.   Generally only one CallIDAnswerLength item should
              be in a modem configuration file.

       CallIDAnswerLength
              An integer indicating the minimum  number  of  characters  in  a
              CallID  matching  the previous CallIDPattern to be received when
              ModemAnswerCmd  is  sent  to  the  modem  irrespective  of   any
              RingsBeforeAnswer  value  greater  than  zero.   This allows the
              answering of calls which deliver CID/DID  data  but  not  RINGs.
              For example,
              CallIDAnswerLength: ‘‘7’’
              would  cause  the  call  to  be  answered when CallID2 reached a
              length of seven digits.  A value of zero for  CallIDAnswerLength
              disables this feature.

       ClocalAsRoot
              Control  whether operations that set the CLOCAL bit on the modem
              device special file are done with the effective user-ID  set  to
              the  super-user or the ‘‘fax’’ user.  By default such operations
              are done as the fax user, except under IRIX where they are  done
              as the super-user (because IRIX disallows manipulation of CLOCAL
              by anyone but the super-user).

       ContCoverCmd¹
              The command to invoke to generate a continuation cover page; see
              ContCoverPage and mkcover(8).

       ContCoverPage¹
              A template file to use in creating continuation cover pages.  If
              this parameter is  non-null,  then  the  server  will  pass  the
              filename  to  the  command specified by ContCoverCmd to generate
              cover pages for outbound jobs that are continued after  protocol
              errors.   These  cover  pages identify the receiver and indicate
              that  the  document  is  a  continued  transmission.   If   this
              parameter  is not specified or is null, then the server will not
              generate continuation cover pages.  The specified pathname  must
              be relative to the top of the fax server’s spooling area.

       CountryCode²
              The local country code in which the facsimile modem resides.  As
              for AreaCode, this value is passed to the dial string rules  for
              use  in  formulating  canonical phone numbers for dialing (among
              other things.)

       CountSkippedPages
              If a page range has been specified in the  job,  and  pages  are
              being  skipped  during  the  send,  this  controls  if the pages
              skipped are counted  in  the  pages  counted  and  totaled.   If
              skipped  pages are to be counted, it will appear as if the pages
              were instantly sent in 0:00 with no data.   The  tagline  counts
              will  be  incremented  on  skipped  pages,  and faxq will notify
              clients via triggers of them as well.  If  the  are  not  to  be
              counted, then tagline page counts will act as if the pages never
              existed, and not faxq trigger notifications will be sent.

       DeviceMode
              The file protection mode that the  server  should  set  for  the
              modem device file.  Note that this value is given in octal.  The
              default value of 0600  implies  that  only  the  facsimile  user
              (usually uucp) can access the modem.  See also chmod(2).

       DialStringRules²
              The  pathname  of  the  file that holds the rules for processing
              user-specified dial strings; c.f.  dialrules(5).  The  specified
              pathname  must  be  relative  to  the  top  of  the fax server’s
              spooling area; e.g.  etc/dialrules.

       DistinctiveRings
              Modern distinctive ring support on  most  modems  indicates  the
              ring   cadence   rather  than  the  older  style  of  ‘‘RING1’’,
              ‘‘RING2’’, etc.  To  indicate  the  ring  cadence,  DRingOn  and
              DRingOff  values  are  presented  by  the  modem to the faxgetty
              process.   The  modem  indicates  the  entire  cadence   between
              ‘‘RING’’ indications Like this:

                RING
                DROF=40
                DRON=8
                DROF=4
                DRON=8
                RING

              The  corresponding  DistinctiveRings  parameter  for  this  ring
              cadence would be:

                DistinctiveRings:  F-8-4-8

              where ‘‘F’’ tells the faxgetty process that the ring cadence  is
              for  a  facsimile  (‘‘V’’ for voice and ‘‘D’’ for data), and the
              other values describe the ring cadence with leading  and  ending
              DRingOff  values  ignored.  Multiple ring cadences are indicated
              by delimiting them with commas in this fashion:

                DistinctiveRings:  V-20,F-8-4-8,D-4-2-4-8

       DRingOff
              A string that identifies the ‘‘off’’ value  in  any  distinctive
              ring  cadence,  for  example  ‘‘DROF=’’.   See  also DRingOn and
              DistinctiveRings.

       DRingOn
              A string that identifies the ‘‘on’’  value  in  any  distinctive
              ring  cadence,  for  example  ‘‘DRON=’’.   See also DRingOff and
              DistinctiveRings.

       DynamicConfig
              The pathname of the optional program, e.g. ‘‘etc/localid’’, that
              makes  dynamic  configuration changes, i.e., to LocalIdentifier,
              based on device ID and  call  identification.   The  program  is
              passed  those  values  as  the  parameters ($1 = device id, $2 =
              CallID1, $3 = CallID2, $4 = CallID3,  ...),  when  answering  an
              incoming call.  The program can then perform local processing as
              desired to send on standard output the  configuration  items  to
              change in a ‘‘parameter:value’’ format, i.e.  ‘‘LocalIdentifier:
              +1.800.555.1212’’.  If  there  are  multiple  parameters  to  be
              changed,  then  each  item  must  be  on  its own line.  This is
              commonly used to dynamically alter the local  identification  of
              systems  which  use  DID/DNIS,  but it can also be used to allow
              different modem  configurations  for  different  senders.   This
              program can also set the RejectCall options to cause the current
              call to be rejected instead of answered.  Note  that  this  file
              must be marked as executable by the faxgetty process.

       EGettyArgs
              A  string that indicates whether or not the server should use an
              an external getty application to deduce and possibly  handle  an
              incoming  call.   If  the  string  value is not null, then it is
              interpreted as a set of arguments to pass to the getty  program.
              Before  supplying the arguments, the string is first scanned for
              ‘‘%’’-escape sequences: any appearance  of  ‘‘%l’’  is  replaced
              with  the tty name and any appearance of ‘‘%s’’ is replaced with
              the serial port speed (in decimal).  Any appearance  of  escaped
              numbers  1 through 9 (‘‘%1’’ through ‘‘%9’’) are replaced by the
              match to the corresponding CallIDPattern, if present.  The ‘‘%’’
              character  can  be  specified  with  ‘‘%%’’.   If the EGettyArgs
              parameter is not specified in the configuration file or  if  the
              string  value  is  null,  then  ‘‘extern’’  connections  will be
              rejected.  Note that in addition to the specified  command  line
              arguments,  the  external  getty  program  is  invoked  with its
              standard input, output, and error descriptors  directed  to  the
              controlling tty device.

              When  the  external getty application completes, its exit status
              is evaluated and is interpreted to indicate what,  if  anything,
              should be done with the call.  An exit status of ‘‘0’’ indicates
              an unknown call type and that the call should be handled  as  if
              the external getty program had not been used.  An exit status of
              ‘‘1’’ indicates a data connection and that the getty(8)  program
              should  be  used  to handle the call (see GettyArgs) after being
              answered with ModemAnswerDataBeginCmd .  An exit status of ‘‘2’’
              indicates  a  fax  connection that should be handled after being
              answered with ModemAnswerFaxBeginCmd.  An exit status  of  ‘‘3’’
              indicates  a  voice  call  and that the vgetty program should be
              used to handle the call (see VGettyArgs)  after  being  answered
              with  BR  ModemAnswerVoiceBeginCmd .  An exit status of ‘‘4’’ is
              considered to be  an  error  condition.   The  session  will  be
              terminated.   An  exit  status of ‘‘5’’ is used to indicate that
              the external getty program handled the call entirely, is not  an
              error  condition,  and  that  the  session  is  to be considered
              terminated.

       FAXNumber
              The phone number associated  with  the  facsimile  modem.   This
              string   is   used   to   generate  the  Transmitter  Subscriber
              Identification (TSI) and Caller Subscriber Identification  (CSI)
              information passed to remote machines—unless the LocalIdentifier
              parameter is explicitly set.  The FAXNumber is also used to name
              the  session log file where information for incoming phone calls
              is recorded; see hylafax-log(5).  If this phone number is not  a
              fully  qualified  number  the values of AreaCode and CountryCode
              are used to generate the transmitted CSI and TSI.

       Include²
              Include the specified file and parse it as a config file

       InternationalPrefix²
              The string to use to place an international phone call.  In  the
              United  States,  this  is ‘‘011’’.  This string is passed to the
              dial string rules.

       JobControlCmd¹
              The command to invoke to which provides Job Control  information
              for a job. See JobControl(8).

       JobReqBusy
              The delay in seconds to wait before retrying a job whose dialing
              attempt failed with a ‘‘BUSY’’ status result.

       JobReqDataConn
              The delay in seconds to wait before  retrying  a  facsimile  job
              whose  dialing  attempt failed because a data modem answered the
              phone.

       JobReqNoAnswer
              The delay in seconds to wait before retrying a job whose dialing
              attempt failed with a ‘‘NO ANSWER’’ status result.

       JobReqNoCarrier
              The delay in seconds to wait before retrying a job whose dialing
              attempt failed with a ‘‘NO CARRIER’’ status result.

       JobReqNoFCon
              The delay in seconds to wait before  retrying  a  facsimile  job
              whose  dialing  attempt  failed  because  the  initial facsimile
              protocol  handshake  failed  (i.e.  no  ‘‘+FCON:’’  result   was
              received from a Class 2/2.0 modem).

       JobReqOther²
              The  delay  in seconds to wait before retrying a job that failed
              for  a  reason  not  already  covered  by  one  of  the  JobReq*
              parameters.

       JobReqProto
              The  delay  in  seconds  to wait before retrying a facsimile job
              that failed because of a fax protocol error.

       JobRetryBusy
              The number of times to redial a phone number after  receiving  a
              ‘‘BUSY’’  result  code when the number has not been successfully
              dialed before.

       JobRetryDataConn
              The number of times to redial a phone number after  the  dialing
              attempt  failed because a data modem answered the phone when the
              number has not been successfully dialed before.

       JobRetryNoAnswer
              The number of times to redial a phone number after  the  dialing
              attempt failed because of NO ANSWER when the number has not been
              successfully dialed before.

       JobRetryNoCarrier
              The number of times to redial a phone number after  the  dialing
              attempt  failed  because  of  NO CARRIER when the number has not
              been successfully dialed before.  In normal  operation  the  fax
              server  will  treat  this  result  code to mean that a facsimile
              modem/machine did not answer the phone and reject  the  transmit
              job.   This  is  done  to  avoid  repeatedly dialing wrong phone
              numbers and depends  on  the  modem  distinguishing  between  no
              carrier  and no answer.  However, some modems are not capable of
              reliably distinguishing between no carrier  and  no  answer,  or
              when  instructed  to  do  so  do  not  identify  a  busy  signal
              correctly.  For these  modems  one  may  find  it  necessary  to
              increase  the  value  of  this  parameter  to compensate.  It is
              strongly recommended, however, that this value not be set  to  a
              large number.

       JobRetryOther
              The  number  of times to redial a phone number after the dialing
              attempt failed for a reason not already covered by  one  of  the
              other   JobRetry*  parameters  when  the  number  has  not  been
              successfully dialed before.

       GettyArgs
              A string that indicates whether or not the server should  invoke
              the getty(8) program in response to an incoming call from a data
              modem.  If the string value is not null, then it is  interpreted
              as  a  set  of  arguments  to pass to the getty program.  Before
              supplying  the  arguments,  the  string  is  first  scanned  for
              ‘‘%’’-escape  sequences:  any  appearance  of ‘‘%l’’ is replaced
              with the tty name and any appearance of ‘‘%s’’ is replaced  with
              the  serial  port speed (in decimal).  Any appearance of escaped
              numbers 1 through 9 (‘‘%1’’ through ‘‘%9’’) are replaced by  the
              match to the corresponding CallIDPattern, if present.  The ‘‘%’’
              character can  be  specified  with  ‘‘%%’’.   If  the  GettyArgs
              parameter  is  not specified in the configuration file or if the
              string value is null, then data connections  will  be  rejected.
              Note  that  in addition to the specified command line arguments,
              the getty program is invoked with its  standard  input,  output,
              and error descriptors directed to the controlling tty device.

       LocalIdentifier
              The local station identification string to use when transmitting
              TSI and CSI strings  (see  FAXNumber  above).   NB:  while  this
              string  may  contain any printable ASCII characters; beware that
              CCITT T.30 specifies a restricted character  set  and  some  fax
              modems  and  machines  may reject or not display  non-conforming
              strings.  If the local identifier is not specified, a  canonical
              form of the FAXNumber is used instead.

       LockDataCalls
              Hold  the  UUCP lockfile during the time an inbound data call is
              processed by the external getty program.  If  this  is  disabled
              then  the lockfile will be removed just before the getty program
              is invoked.  Note however that  doing  this  introduces  a  race
              condition  whereby  an  outbound  program  may sneak in and take
              control of the modem after the inbound call has  been  accepted,
              but  before  the getty program has started up and installed it’s
              own lockfile.

       LockVoiceCalls
              Hold the UUCP lockfile during the time an inbound data  call  is
              processed  by  the  external  voice  getty  program.  If this is
              disabled then the lockfile will be removed just before the voice
              getty   program  is  invoked.   Note  however  that  doing  this
              introduces a race condition  whereby  an  outbound  program  may
              sneak  in  and  take control of the modem after the inbound call
              has been accepted,  but  before  the  voice  getty  program  has
              started up and installed it’s own lockfile.

       LogFacility²
              The symbolic name for the syslog(3) facility to use when logging
              error messages and  informational/debugging  messages  requested
              through the ServerTracing parameter.  The list of facility names
              is standardized; it can be found  in  the  system  include  file
              <syslog.h>; comparisons are case-insensitive.

       LogCalls
              Log  all  incoming  calls into xferfaxlog as CALL records.  This
              allows a quick check of all incoming calls,  regardless  of  fax
              completion or not in a unified manner with other fax logs.

       LogFileMode
              The file protection mode that should be used when creating files
              to hold session logs.  Note that this value is given  in  octal.
              The  default  value  of  0600 implies that the log files are not
              generally  accessible,   which   is   important   if   sensitive
              information  such  as  calling card access codes are logged.  If
              log files are to be publicly accessible, this value may be  set,
              for example, to 0644.  See also chmod(2).

       LongDistancePrefix²
              The  string  to use to place a long distance phone call.  In the
              United States, this is ‘‘1’’.

       MaxConcurrentCalls¹
              The default value to use for the maximum number of jobs for  the
              same  destination  that  are  processed concurrently.  Thus this
              parameter defines the maximum number of concurrent  phone  calls
              to  the  same  destination.  Unless all of your fax destinations
              have  multiple  fax  lines  using  the  same  fax   number   per
              destination then MaxConcurrentCalls is probably best left as the
              default of 1  and  exceptions  should  be  accommodated  by  the
              JobControl mechanism.

       MaxBatchJobs¹
              The maximum number of jobs to batch together in a single call.

       MaxConsecutiveBadLines
              The  maximum  number of consecutive erroneous rows of image data
              that the server will receive before it  deems  a  page  to  have
              unacceptable  copy  quality.   Setting  this  parameter  to zero
              causes  the  server  to  not  check  the  quality  of   received
              facsimile.  Facsimile received with error-correction do not have
              copy quality checking performed.  See also PercentGoodLines.

       MaxDials¹
              The default value for the maximum number  of  times  the  server
              will  place  a  call  for  an  outbound  job.  This value may be
              overridden by rules  in  the  JobControl  mechanism.   See  also
              MaxTries.

       MaxRecvPages
              The maximum number of pages the server will accept in a received
              facsimile before it aborts the session.

       MaxSendPages¹
              The default value for the maximum number  of  pages  the  server
              will  permit  in  a  transmitted  facsimile.  Outbound jobs that
              exceed this limit are rejected.  This value may be overridden by
              rules in the JobControl mechanism.

       MaxSetupAttempts
              The  maximum  number  of  times  a  HylaFAX  server program will
              attempt to initialize a modem before considering it  ‘‘wedged’’.

       MaxTries¹
              The  default  value  for  the maximum number of times the server
              will attempt to communicate with a remote site.  Note that for a
              call   to  be  counted  against  this  limit,  carrier  must  be
              established; this is in contrast to the value of MaxDials  which
              limits  the  number  of calls that will be placed on behalf of a
              job.  This value may be overridden by rules  in  the  JobControl
              mechanism.  See also MaxDials.

       MinAcceptedLineCount
              The  minimum  number  of received scanlines allowed on an ‘‘OK’’
              page.  The use of this setting prevents confirmation from  being
              sent for very short pages.

       ModemGroup¹
              Define  a  logical  name  for  a  set  of  modem  devices.  This
              parameter can be used to define a name that clients can  use  to
              refer  to  a  collection  of  modems.   The  syntax  is ‘‘<name>
              <regex>’’ where <name> is the name for the group and <regex>  is
              a  regular expression that faxq(8) matches against known modems.
              Thus for example, the default modem to use for a  job,  any,  is
              defined as ‘‘any:.*’’.  This parameter may be specified multiple
              times to define  multiple  modem  classes.   Modem  classes  may
              overlap.   The  actual  set  of modems in a modem class that are
              considered for use may vary based on which modems  are  believed
              to be ready for use.

       ModemPriority
              The scheduling priority to use for a modem.  Priority values are
              in the range 0 to 255 with lesser values signifying higher (more
              desirable)  priority.  The HylaFAX scheduler process assigns the
              highest priority modem that is ready for use when scheduling  an
              outbound job.

              If multiple available modems in a job’s selected ModemGroup have
              the same ModemPriority value, then the HylaFAX scheduler assigns
              jobs to them in a round-robin fashion.

       NoAnswerVoice
              Whether  or  not  to disable the answering of calls indicated as
              voice (e.g. by DistinctiveRings ).

       NoCarrierRetrys
              This is mapped onto JobRetryNoCarrier

       ModemReadyState
              Define the state transmitted to the  HylaFAX  scheduler  process
              each time a modem is made ready by a faxgetty process.  State is
              one of: ‘‘R’’ (ready for use), ‘‘B’’ (busy),  or  ‘‘D’’  (down).
              The modem state can be used to control whether or not modems are
              assigned to outbound jobs.  A modem’s state is initially set  to
              ‘‘R’’  (ready).  Modem state can be dynamically changed with the
              faxstate(8) program or by setting this  configuration  parameter
              with the faxconfig(8) program.

       ModemRingResponse
              This   can   be   used   to   cause   the   command  defined  by
              ModemRingResponse to be sent to the modem after hearing at least
              ModemRingsBeforeResponse  RINGs  in  order  to  receive DID-DTMF
              data, for example.

       ModemRingsBeforeResponse
              This defines the minimum number of  RINGs  that  must  be  heard
              before ModemRingResponse is first sent to the modem.

       NotifyCmd²
              The command to invoke to notify a client of a job status change;
              see notify(8).

       PageChop¹
              Whether or not to automatically truncate trailing whitespace  on
              pages  of  outbound facsimile (when possible).  If page chopping
              is enabled, then pages with at least PageChopThreshold  trailing
              whitespace  on a page will be transmitted as a ‘‘short page’’ if
              the receiver is capable of accepting variable-length pages.  The
              possible  values  are:  ‘‘last’’  to enable chopping of the last
              page of each document, ‘‘all’’ to enable chopping of all  pages,
              or ‘‘none’’ to disable page chopping.

       PageChopThreshold¹
              The  minimum  amount of trailing whitespace that must be present
              on a page before page chopping will be attempted; see  PageChop.
              Note that this value is specified in inches.

       PCL2FaxCmd¹
              The command to invoke to convert a HP-PCL document submitted for
              transmission to TIFF/F, suitable for transmission.

       PercentGoodLines
              The minimum percentage of good rows of image data required for a
              received  facsimile  page  to  be deemed to have acceptable copy
              quality.  Setting this parameter to zero causes  the  server  to
              not check the quality of received facsimile.  Facsimile received
              with  error-correction  do  not  have  copy   quality   checking
              performed.  See also MaxConsecutiveBadLines.

       PollLockPokeModem
              When  polling  for the presence/removal of a UUCP lockfile, also
              test to make sure the modem is still reachable.  This is  useful
              for  scenarios  where  the  modem  is apt to become disconnected
              while the modem is idle, such as an external modem that may lose
              power,  where the administrator wants notification of this (as a
              ‘‘wedged’’ condition).

       PollLockWait
              When polling for the presence/removal of a  UUCP  lockfile,  the
              time  (in  seconds)  to  wait  between checks.  Lockfile polling
              occurs to ensure the fax server  doesn’t  collide  with  another
              process using the modem.

       PollModemWait
              The  time  (in  seconds)  to  wait between checks for a modem to
              become ready for use.  Modem polling occurs when a  modem  fails
              to reset cleanly.

       PriorityScheduling
              Indicates whether the HylaFAX scheduler should utilize available
              priority  job  scheduling   mechanisms   to   enhance   realtime
              execution,  particularly with Class 1 configurations on older or
              slower systems.

              Currently PriorityScheduling is available for IRIX,  SVR/4,  HP-
              UX,  and  POSIX-compliant  (i.e.  Linux) operating systems.  The
              default value varies to maintain traditional  HylaFAX  behavior.
              On  IRIX,  SVR/4,  and  HP-UX systems where the configure script
              detects one of the functions schedctl(), priocntl() or  rtprio()
              the   default  is  true.   The  only  other  supported  priority
              mechanism is POSIX sched_setscheduler(), which is used on Linux,
              OpenServer and possibly other systems.  On such systems, as well
              as on systems where no priority scheduling mechanism exists, the
              default is false."

       PS2FaxCmd¹
              The command to invoke to convert a POSTSCRIPT document submitted
              for transmission  to  TIFF/F,  suitable  for  transmission;  see
              ps2fax(8).

       QualifyPWD
              A  string  that specifies whether or not the identity of calling
              facsimile machines should be checked against an  access  control
              list  before  receiving  facsimile.   If QualifyPWD is non-null,
              then only messages from facsimile  machines  identified  in  the
              file  specified  by  the  string  (typically etc/passwd) will be
              accepted; similar to QualifyTSI.

       QualifyTSI
              A string that specifies whether or not the identity  of  calling
              facsimile  machines  should be checked against an access control
              list before receiving facsimile.   If  QualifyTSI  is  non-null,
              then  only  messages  from  facsimile machines identified in the
              file  specified  by  the  string  (typically  etc/tsi)  will  be
              accepted;  see  tsi(5).   If  QualifyTSI is not specified in the
              configuration file, or the value  is  null,  then  all  incoming
              facsimile messages will be accepted.

       RecvDataFormat
              The data format (compression scheme) to write received facsimile
              data when copy quality checking is performed on the host.  (When
              copy  quality  checking  is  not done by the server, for example
              when error correction protocol is used, the  received  facsimile
              data  is written exactly as it is received from the modem.)  The
              format may be one: ‘‘1-D  MH’’,  ‘‘2-D  MR’’,  ‘‘2-D  MMR’’,  or
              ‘‘adaptive’’.   An  ‘‘adaptive’’ format causes the received data
              to be written using the data format negotiated by the sender and
              receiver.   Note  that while 2-D MMR is the most space-efficient
              data format the resultant file  may  not  be  viewable  (certain
              commonly  used  programs  do  not properly read multi-strip TIFF
              with 2-D MMR data).

       RecvFileMode
              The file protection mode that should be used when creating files
              to  hold  incoming  facsimile.  Note that this value is given in
              octal.   The  default  value  of  0600  implies  that  only  the
              facsimile   user  can  read  received  facsimile.   If  incoming
              facsimile are to be publicly accessible, this value may be  set,
              for example, to 0644.  See also chmod(2).

       RejectCall
              If  this  is set to true, the current call will not be answered,
              and will be rejected.  This option has no effect if set  in  the
              configuration  file,  but when set by the DynamicConfig program,
              controls the current call.  This options supersedes the obsolete
              QualifyCID option.

       RingData
              A  modem  status string that identifies that an incoming call is
              for data use.  This string should be set when a phone  line  has
              been  setup with distinctive ring service.  See also RingFax and
              RingVoice.

       RingExtended
              An identifier which matches the initial portion of  an  extended
              RING  message  sent  by  the modem to relay CID and/or DNIS data
              instead of sending it formatted on separate lines.

       RingFax
              A modem status string that identifies that an incoming  call  is
              for  facsimile use.  This string should be set when a phone line
              has been setup with distinctive ring service.  See also RingData
              and RingVoice.

       RingsBeforeAnswer
              The number of rings to wait before answering the phone.  If this
              value is set to 0, then the  phone  will  only  be  answered  in
              response to an explicit answer command; see faxanswer(8).

       RingTimeout
              If  a ring is heard and the call is not answered, the time in ms
              to wait before reinitializing the modem for the next call.

       RingVoice
              A modem status string that identifies that an incoming  call  is
              for  voice use.  This string should be set when a phone line has
              been setup with distinctive ring service.  See also RingData and
              RingFax.

       RTNHandlingMethod
              Specifies  how  to  react  to  an  RTN  signal received from the
              remote:  one  of   ‘‘Retransmit’’,   ‘‘Giveup’’,‘‘Ignore’’,   or
              ‘‘Retransmit-Ignore’’.

              ‘‘Retransmit’’   assumes   that   the   page   is  not  received
              successfully.  HylaFAX will make up to two  additional  attempts
              to send the page, decreasing signalling rate and retraining.  If
              RTN continues, up to 2 additional calls  will  be  placed.   The
              downside  is  that  if  the remote always responds with RTN, the
              page will be sent 9 times and no following pages will  be  sent.
              Many  fax  machines  will  not  behave  this  way, although T.30
              specification seems clear that this is the  intent  of  the  RTN
              signal.

              Many  fax machines will interpret RTN as meaning to not send the
              same data again.  That is because RTN may indicate problems with
              flow   control,   incorrectly   encoded   T.4   data,   or  some
              incompatibility  other  than  line  noise.   Fax  machines  that
              interpret  RTN  this  way  will  disconnect and require a manual
              retransmission.   This  ‘‘over  and  out’’  behaviour   can   be
              activated  by  the  ‘‘Giveup’’  value.   The  advantage  to this
              behavior is that the same page of image data will  not  be  sent
              multiple  times,  but  the  downside is that the following pages
              will not be sent.

              ‘‘Ignore’’ is  similar  to  ‘‘Giveup’’  in  that  it  makes  the
              assumption  the  data  cannot  be  automatically accepted by the
              receiver.  However, rather than disconnecting the page of  image
              data  is  abandoned  and  processing  moves on to the next.  The
              remote is left to decide what to do with the  unacceptable  page
              of  image  data.   The  downside  to  this behavior, is that the
              remote may or may not have  kept  the  page,  depending  on  its
              interpretation  of  the  RTN  signal  -  but it does allow us to
              continue on to the next page.

              ‘‘Retransmit-Ignore’’ is a  combination  of  ‘‘Retransmit’’  and
              ‘‘Ignore’’.   The  page of image data is retransmitted up to two
              additional times, but rather than disconnecting  after  a  third
              RTN  signal  for  the same page, processing then continues on to
              the next page.  This approach  is  an  effort  to  satisfy  both
              interpretations  of  an  RTN  signal.  It allows the receiver to
              hopefully receive a better copy of  the  image  data  while  not
              failing  to  send  subsequent  pages.   If the receiver saves or
              prints a copy of pages for which it transmits RTN, then it could
              save or print up to three copies of every page.

       SaveUnconfirmedPages
              Whether  or  not  to save a received facsimile image page if the
              sender  disconnects  without  sending  the  post-page   message,
              without  hearing our message confirmation, without retraining as
              requested, or otherwise breaks fax protocol following such pages
              for which the sender should not have a ‘‘receipt confirmation’’.

       SendFaxCmd¹
              The command to use  to  process  outbound  facsimile  jobs;  see
              faxsend(8).

       SendPageCmd¹
              The   command  to  use  to  process  outbound  pager  jobs;  see
              pagesend(8).

       SendUUCPCmd¹
              The  command  to  use  to  process  outbound  UUCP  jobs.   This
              parameter is not currently used, it is for future development.

       ServerTracing²
              A  number that controls the generation of tracing information by
              a server when  not  actively  sending  or  receiving  facsimile.
              Tracing  is divided into areas that are individually controlled.
              To enable tracing of  multiple  areas  of  operation,  the  flag
              associated  with  each area should be bit-or’d to form the value
              for this tag.
              Flag                Area                    Description

              For example, to enable tracing of server operations and protocol
              operations,  a  value of 1+2=3 should be specified.  NB: tracing
              timeouts and/or  binary  modem  I/O  can  adversely  affect  the
              operation of the fax server; enabling these areas should be done
              with extreme care.

              Server tracing is  directed  to  syslog(3)  using  the  facility
              specified  with  the  LogFacility configuration parameter.  Note
              that syslogd(8) must be  configured  to  capture  facility.info,
              facility.debug,  facility.warning,  and  facility.err  messages.
              See hylafax-log(5) for a description of the logged messages.

       SessionTracing²
              A number that controls the generation of tracing information  by
              a  server  while  sending or receiving facsimile.  The number is
              interpreted identically to  ServerTracing.   Note  that  session
              tracing  is  placed  in  log  files in the log subdirectory; see
              hylafax-log(5) for more information.

       SpeakerVolume
              The volume level that the in-modem speaker should be adjusted to
              while in command mode.  The possible values are:
              Value     Description
              Off       silent
              Quiet     almost inaudible
              Low       tolerable in privacy
              Medium    loud enough to hear in the next room
              High      intolerable
              Note  that  the  speaker  is  always  turned off once carrier is
              established.  Also beware that some modems support fewer  volume
              settings; see ModemSetVolumeCmd.

       TagLineCoverNumString

              Setting  TagLineCoverNumString  instructs faxsend to not include
              the cover pages in the normal  page  numbering  mechanism.   The
              page numbers used in the tagline generation will adjusted to not
              count the cover pages, and the TagLineCoverNumString  value  wil
              be  used  instead  of  a page number on the tagline of the cover
              page.

       TagLineFont
              The filename of the font to use in imaging tag lines across  the
              top  of  each  transmitted  page.   Fonts  must be stored in the
              Portable Compiled Font (PCF)  format  used  by  the  X11  Window
              System.   Filenames  are  specified  relative to the root of the
              spooling area; e.g. etc/lutRS18.pcf.  If no font  is  specified,
              if  a  null filename is specified, or if the specified font file
              is not readable, then tag lines will not be generated.  See also
              TagLineFormat.

       TagLineFormat
              The  format  string to use when imaging tag lines across the top
              of each transmitted page.  This string may include escape  codes
              that  cause various items to be interpolated into the imaged tag
              line.  Any escape code supported by strftime(3C) may be used  as
              well as the following server-implemented codes:
              Escape    Description
              %%a       destination subaddress
              %%c       destination company name
              %%C       sender’s company name
              %%d       destination phone number
              %%g       destination geographic location
              %%G       sender’s geographic location
              %%i       job identifier
              %%I       group identifier
              %%j       user-specified job tag
              %%l       LocalIdentifier or canonicalized FAXNumber
              %%m       sender’s electronic mail address
              %%n       canonicalized FAXNumber
              %%p       current page number of session
              %%P       current page number of job
              %%r       receiver’s name
              %%s       sender’s name
              %%S       subject
              %%t       total pages in session
              %%T       total pages in job
              %%v       destination voice number
              %%V       sender’s voice number
              %%%       ‘‘%’’
              In  addition,  the format string may indicate that text is to be
              centered in multiple equal-sized fields by separating text  with
              ‘‘|’’  characters.   For  example, ‘‘a|b|c’’ would cause the tag
              line to be broken up  into  three  equal-sized  areas  with  the
              strings  ‘‘a’’,  ‘‘b’’,  and  ‘‘c’’ centered within each region.
              The default tag line format string is ‘‘From %%n|%c|Page %%P  of
              %%T’’.   The  differences  between the %%p or %%P and the %%t or
              %%T options are noticed when a  fax  job  is  retried  after  an
              incomplete attempt and only the previously unsent pages are then
              queued in a successive session.  See also TagLineFont.

       TIFF2FaxCmd¹
              The  command  to  invoke  to  convert  a  TIFF   submitted   for
              transmission   to   TIFF/F,   suitable   for  transmission;  see
              tiff2fax(8).

       TimeOfDay¹
              The default time-of-day restrictions to apply to outbound  jobs.
              Outbound  jobs will be processed only during the specified time.
              Any jobs submitted outside this time period will be  held  until
              the start of this time.  The syntax for time-of-day restrictions
              is designed to be compatible with the syntax used  by  the  UUCP
              software.  The following BNF describes the syntax:
                 Syntax = tod ["," tod]
                    tod = <days><timerange>
                   days = "Any" | "Wk" | <dayname>+ | nothing
                dayname = "Sun" | "Mon" | "Tue" | "Wed" | "Thu" | "Fri" | "Sat"
              timerange = <start> "-" <end> | nothing
                  start = <24hrtime>
                    end = <24hrtime>
               24hrtime = {0-9}{0-9}{0-9}{0-9}
                nothing =
              where  start  and end are 24-hour times, day names can be either
              2- or 3-characters, and a null day or time  specification  means
              any  time  or day.  White space and other syntactic sugar may be
              freely inserted between tokens but may not be  inserted  between
              24-hour times in the time range.

              This  value  may  be  overridden  by  rules  in  the  JobControl
              mechanism.

       Use2D¹ Control the use of 2D-encoded data for transmitted facsimile.

       UseJobTagLine
              Allow the use  of  the  job-specified  tagline  instead  of  the
              configured TaglineFormat

       UUCPLockMode²
              The  file protection mode that should be used when creating UUCP
              lockfiles.  Note that this value is given in octal.

       UUCPLockDir²
              The pathname of the directory in which UUCP lockfiles are to  be
              created.

       UUCPLockTimeout²
              The  time  in  seconds  to  wait  before  removing  a stale UUCP
              lockfile (i.e. a lockfile whose owner does not appear to exist).
              If this value is set to 0, then the fax server will never remove
              a stale lockfile.

       UUCPLockType²
              A string that specifies the type of  UUCP  lockfile  to  create.
              The  string  may  be one of ‘‘ascii’’ or ‘‘binary’’ depending on
              whether the process-ID of the lock owner is written to the  file
              as  an  ascii  string  or  as  a binary value, respectively.  In
              addition, two prefixes may be used to control the format of  the
              lock  filename.   If  the  type string is prefixed with a ‘‘+’’,
              then SVR4-style filenames are generated using the  major  device
              number  of the tty device and the major and minor device numbers
              for the filesystem on which the tty device resides.  If the type
              string  is prefixed with a ‘‘-’’, then any upper case letters in
              the device part of the lockfile name are converted to lower case
              letters;   for   example,   ‘‘LCK..ttyA01’’   is   converted  to
              ‘‘LCK..ttya01’’.  This upper-to-lower case conversion is  useful
              for  systems such as SCO where the convention is to name devices
              with upper-case letters, but create  lockfiles  with  lower-case
              letters.

       VGettyArgs
              A  string that indicates whether or not the server should invoke
              a voice getty program in response to an incoming voice call.  If
              the string value is not null, then it is interpreted as a set of
              arguments to pass to the vgetty program.  Before  supplying  the
              arguments,   the   string  is  first  scanned  for  ‘‘%’’-escape
              sequences: any appearance of ‘‘%l’’ is  replaced  with  the  tty
              name  and  any  appearance of ‘‘%s’’ is replaced with the serial
              port speed (in decimal).  Any appearance of  escaped  numbers  1
              through  9  (‘‘%1’’ through ‘‘%9’’) are replaced by the match to
              the  corresponding  CallIDPattern,  if   present.    The   ‘‘%’’
              character  can  be  specified  with  ‘‘%%’’.   If the VGettyArgs
              parameter is not specified in the configuration file or  if  the
              string  value  is null, then voice connections will be rejected.
              Note that in addition to the specified command  line  arguments,
              the  vgetty  program is invoked with its standard input, output,
              and error descriptors directed to the controlling tty device.

       WedgedCmd¹
              The command to invoke when a modem  is  deemed  ‘‘wedged’’;  see
              wedged(8).

MODEM-ORIENTED CONFIGURATION PARAMETERS

       This  section  lists  configuration parameters that are specific to the
       setup and operation of the  modem.   All  commands  must  be  specified
       exactly as they are to be transmitted to the modem (note that this is a
       departure from previous versions of this  software  that  automatically
       prepended  ‘‘AT’’  to  each  line of commands sent to the modem).  When
       multi-line commands are required, enclose the commands in  quote  marks
       (‘‘"’’)  and  insert  a  newline character ‘‘\n’’ where lines should be
       broken.    An   example   of   a   multi-line   command    string    is
       ‘‘AT+FCQ=1\nAT+FBADMUL=20\nAT+FBADLIN=10’’.

       Command  strings  sent  to  the  modem may include command escapes that
       force the host to  alter  the  DTE-DCE  communication  rate,  the  flow
       control  scheme  used between the host and modem, delay for a period of
       time, flush input data, and wait  for  a  specific  response  from  the
       modem.  The following escape codes are interpreted:
              Escape             Effect
              <none>             enable no flow control between DTE and DCE
              <xon>              enable software flow control between DTE and DCE
              <rts>              enable hardware flow control between DTE and DCE
              <2400>             set the DCE-DTE baud rate to 2400 bps
              <4800>             set the DCE-DTE baud rate to 4800 bps
              <9600>             set the DCE-DTE baud rate to 9600 bps
              <19200>            set the DCE-DTE baud rate to 19200 bps
              <38400>            set the DCE-DTE baud rate to 38400 bps
              <57600>            set the DCE-DTE baud rate to 57600 bps
              <76800>            set the DCE-DTE baud rate to 76800 bps
              <115200>           set the DCE-DTE baud rate to 115200 bps
              <delay:N>          delay N x 10 ms on the host (0 <= N <= 255)
              <flush>            flush any pending input data from the modem
              <waitfor:R>        wait for the response R from the modem (see below)
              <play:filename>    play the specified audio file (see below)
       Note  that commands to the left of an escape code are sent to the modem
       before the associated actions are carried out on the host.  This may be
       important  when  changing baud rates, as the result code from a command
       may be returned at the new baud rate.  Also, beware that not  all  baud
       rates  are  supported  by all systems and modems; the set of baud rates
       supported by a host is usually listed in stty(1).

       The ‘‘<waitfor:..>’’  escape  can  be  used  to  override  the  default
       behaviour  which is to wait for an ‘‘OK’’ response to a command sent to
       the modem.  The possible response codes are:
              NOTHING       a null response
              OK            the default response
              CONNECT       ‘‘CONNECT...’’
              NOANSWER      ‘‘NO ANSWER...’’
              NOCARRIER     ‘‘NO CARRIER...’’
              NODIALTONE    ‘‘NO DIALTONE...’’
              BUSY          ‘‘BUSY’’
              OFFHOOK       ‘‘PHONE OFF-HOOK’’
              RING          ‘‘RING...’’
              ERROR         error status from modem
              VCON          voice connection indicator
              OTHER         any unrecognized modem response
       For example ‘‘ATO\r<waitfor:CONNECT>’’  would  send  ‘‘ATO\r’’  to  the
       modem  and  then  wait for a response with a leading ‘‘CONNECT’’ in it;
       and    ‘‘ATS99=2\r<delay:2><flush><waitfor:NOTHING>’’    would     send
       ‘‘ATS99=2\r’’  to  the  modem,  delay  20  ms, flush any input from the
       modem, and then continue (not wait for any response).

       The ‘‘<play:filename>’’ escape can be used to play  a  raw  audio  file
       with  a voice modem.   This feature can be used, for example, to play a
       brief audio message after picking up the line but before answering.   A
       configuration example may be:

         ModemRingResponse:  "AT+FCLASS=8;H1\nAT+VSM=131\nAT+VLS=1\nAT+VTX\n<waitfor:CONNECT><play:/sounds/enter-extension.raw><waitfor:OK>AT+VTS=[933,,150]"
         ModemAnswerCmd:     "<delay:100>AT+FCLASS=1;A"
         CallIDPattern:      SHIELDED_DTMF
         CallIDAnswerLength: 4

       In   this  example  using  an  IS-101  voice-compliant  modem,  a  RING
       indication from the modem will cause the modem to be  placed  in  voice
       mode, set ulaw audio compression, and via the connected phone line play
       back the etc/play1.raw audio file, which may say, "After the tone enter
       a  four-digit  extension, then start the fax."  Following the message a
       tone is played.

       ModemAnswerCmd
              The command to answer the  phone.   If  possible,  this  command
              should  generate  a  result  string  that identifies whether the
              incoming call  is  from  a  facsimile,  voice,  or  data  modem.
              Typically  this auto-detection is configured ahead of time; e.g.
              for Class 2 modems with the ‘‘AT+FAA=1’’ command.

              The  following  table  describes  how  the  result   codes   are
              interpreted by the facsimile server.
              Result String    Default          Class 1      Class 2      Class2.0
              CONNECT FAX      Fax              -            -            --
              CONNECT          Data             Unknown      -            -
              NO ANSWER        No Answer        -            -            -
              NO CARRIER       No Carrier       -            -            -
              NO DIALTONE      No Dialtone      -            -            -
              ERROR            Error            -            -            -
              FAX              Fax              -            -            -
              DATA             Data             -            -            -
              +FCON            -                -            Fax          Fax
              +FCO             -                -            Fax          Fax
              +FDM             -                -            Data         Data
              +FHNG:           -                -            Error        Error
              VCON             -                -            Voice        Voice
              The ‘‘Default’’ column indicates the interpretation made for the
              result  string  in  either  class  1  or  2  unless   explicitly
              overridden.   The  ‘‘Class  1’’  column indicates result strings
              handled specially for modems operating in class 1,  the  ‘‘Class
              2’’  column  indicates  special handling for modems operating in
              class 2, and the ‘‘Class 2.0’’ column indicates special handling
              for  modems  operating in class 2.0.  Unknown entries imply that
              interpretation is based  on  the  way  in  which  the  call  was
              answered;  if  answering is done for an explicit call type, that
              type is assumed, otherwise a Fax call is presumed.

       ModemAnswerDataBeginCmd
              The command to send to the modem once a data connection has been
              established.

       ModemAnswerDataCmd
              The   command   to  explicitly  answer  the  phone  for  a  data
              connection.  This command must generate  a  result  string  that
              identifies  the  incoming  call  is  from a data modem.  If this
              parameter is not  specified  or  is  null,  then  the  value  of
              ModemAnswerCmd  is  used  instead.   See also AdaptiveAnswer and
              AnswerRotary.

       ModemAnswerDialCmd
              The  command  to  explicitly  answer  the  phone  for  a  dialed
              connection.   This  command  must  generate a result string that
              identifies the incoming call is from a facsimile modem.  If this
              parameter  is  not  specified  or  is  null,  then  the value of
              ModemAnswerCmd is used instead.

       ModemAnswerFaxBeginCmd
              The command to send to the modem once a facsimile connection has
              been established.

       ModemAnswerFaxCmd
              The  command  to  explicitly  answer  the  phone for a facsimile
              connection.  This command must generate  a  result  string  that
              identifies the incoming call is from a facsimile modem.  If this
              parameter is not  specified  or  is  null,  then  the  value  of
              ModemAnswerCmd  is  used  instead.   See also AdaptiveAnswer and
              AnswerRotary.

       ModemAnswerVoiceBeginCmd
              The command to send to the modem once  a  voice  connection  has
              been established.

       ModemAnswerVoiceCmd
              The   command  to  explicitly  answer  the  phone  for  a  voice
              connection.  This command must generate  a  result  string  that
              identifies the incoming call is for voice.  If this parameter is
              not specified or is null, then the value  of  ModemAnswerCmd  is
              used instead.  See also AdaptiveAnswer and AnswerRotary.

       ModemAnswerResponseTimeout
              The  maximum  time, in milliseconds, to wait for a response from
              the modem after sending ModemAnswerCmd.  Note that you may  want
              to  shorten  this  value  when  using  the server-based adaptive
              answer strategy; see AdaptiveAnswer.

       ModemATCmdDelay
              A delay, in milliseconds, that should be performed  before  each
              ‘‘AT’’ command string is sent to the modem.

       ModemBaudRateDelay
              The  amount of time, in milliseconds, to pause after setting the
              baud rate on the serial line.  This is only needed for hosts and
              modems  (such  as USRs) where setting the serial line parameters
              does not take effect immediately.

       ModemCommaPauseTimeCmd
              The command to set the time, in seconds, that the  modem  should
              pause  when encountering a ‘‘,’’ modifier in the dialing string.

       ModemDialCmd
              The command to place a phone call.  The string is assumed to  be
              suitable  for use as a parameter to the sprintf(3S) function; so
              the ‘‘%’’ character should  be  escaped  as  ‘‘%%’’.   The  dial
              command must include a single ‘‘%s’’ where the number that is to
              be dialed is to be substituted.   Facilities  such  as  tone  or
              pulse  dialing,  outgoing prefixes to route though a PBX, and so
              on should be included in the dialing command string.  It is also
              important  that,  if possible, a trailing ‘‘@’’ symbol should be
              included so that the modem returns result codes that distinguish
              between  no answer and no carrier.  Use of the ‘‘@’’ permits the
              server  to  reduce  the  probability  that  a  wrong  number  is
              continually  redialed.   If  the  modem  does  not  support this
              facility, then it may  be  necessary  to  raise  the  number  of
              retries done when a ‘‘NO CARRIER’’ result is returned.

       ModemDialResponseTimeout
              The  maximum  time to wait, in milliseconds, for a response from
              the modem after sending This value should  be  longer  than  the
              timeout  programmed  into the modem through the ModemWaitTimeCmd
              parameter.  This additional server-based timeout is provided  to
              guard  against  modems  that  can  ‘‘lock  up’’ when dialing the
              telephone.

       ModemDoPhaseCDebug
              Whether or not to query the modem  for  responses  during  image
              data  transmission.   Normally  the modem should not produce any
              responses during Phase C data transmission.   However,  in  some
              debugging  scenarios  (i.e.  some  Class  2.1  modems  may  show
              debugging information) it may be appropriate to query the  modem
              for responses during the data transmission.

       ModemDTRDropDelay
              The  time, in milliseconds, to pause between placing DTR OFF and
              DTR ON while resetting a modem.  This value should be  at  least
              equal  to  the  time-value  of the analogous S-register, usually
              S25.

       ModemEchoOffCmd
              The command to disable echoing of commands sent to the modem.

       ModemFlowControl
              The type of flow control to use between  DTE  and  DCE;  one  of
              ‘‘NONE’’,  ‘‘XONXOFF’’  and  ‘‘RTSCTS’’.   This value is used to
              select the string sent to the modem to initially establish  DTE-
              DCE  flow  control; one of ModemNoFlowCmd, ModemSoftFlowCmd, and
              ModemHardFlowCmd.  The current flow control setting is also used
              to  select  the  appropriate flow control command to send to the
              modem when the software switches to Class  1,  2,  or  2.0;  see
              Class1HFLOCmd,   Class1NFLOCmd,   Class1SFLOCmd,  Class2HFLOCmd,
              Class2NFLOCmd, and Class2SFLOCmd.

              The server supports both software and hardware flow control  for
              Class 1, Class 2, and Class 2.0 modems.  Whether to use hardware
              or software flow control depends  on  the  capabilities  of  the
              modem and the host hardware and operating system.  Communication
              rates above 9600 baud often require that hardware  flow  control
              be  used  for  reliable  DTE-DCE communication.  However, beware
              that many modems only support software flow control when sending
              or receiving facsimile.

              Note  that  modems usually support software flow control even if
              they have no explicit AT-command to activate it; in this case it
              is   switched   on  when  the  modem  enters  fax  mode,  having
              AT+FCLASS=... from DTE.

       ModemFrameFillOrder
              The bit order to expect for received HDLC frames and to use when
              formulating  HDLC  frames  to  send.   This  value may be either
              LSB2MSB when bits  are  ordered  from  least-significant-bit  to
              most-significant-bit  (as in the CCITT specification) or MSB2LSB
              when bits are ordered in the reverse direction.

       ModemHardFlowCmd
              The command to setup hardware (RTS/CTS) flow control between DTE
              and DCE.

       ModemMinSpeed
              The   minimum   acceptable   signalling  rate  for  transmitting
              facsimile page data.  Possible values  are:  2400,  4800,  7200,
              9600, 12200, and 14400.

       ModemMfrQueryCmd
              The  command  to  send  to  the  modem  to  get the manufacturer
              identification string.  If this parameter is not set, then it is
              initialized   to   ‘‘AT+FMFR?’’   for  Class  2  modems,  or  to
              ‘‘AT+FMI?’’ for Class 2.0 modems, or to  ‘‘ATI3’’  for  Class  1
              modems.   If  the  parameter  begins  with  a  ‘‘!’’,  then  the
              remainder of the string is taken to be the identification string
              and no command is issued to the modem.

       ModemModelQueryCmd
              The command to send to the modem to get the model identification
              string.  If this parameter is not set, then it is initialized to
              to  ‘‘AT+FMDL?’’ for Class 2 modems, or to ‘‘AT+FMM?’’ for Class
              2.0 modems, or to ‘‘ATI0’’ for Class 1 modems.  If the parameter
              begins  with  a ‘‘!’’, then the remainder of the string is taken
              to be the identification string and no command is issued to  the
              modem.

       ModemNoAutoAnswerCmd
              The  command to stop the modem from automatically answering when
              the phone rings.

       ModemNoAutoAnswerCmdDelay
              The time, in milliseconds,  to  pause  after  receiving  the  OK
              following  ModemNoAutoAnswerCmd  before any further commands are
              sent to the modem.  All input from the modem  is  flushed  after
              pausing.

       ModemNoFlowCmd
              The command to disable flow control between DTE and DCE.

       ModemOnHookCmd
              The command to place the phone ‘‘on hook’’ (i.e. hangup).

       ModemPageDoneTimeout
              The  maximum  time to wait, in milliseconds, for a response from
              the modem after sending a page of facsimile data (e.g.  the time
              to wait for a response to a Class 2/2.0 AT+FET command).

       ModemPageStartTimeout
              The  maximum  time  to  wait,  in  milliseconds,  for an initial
              response from the modem when sending a page  of  facsimile  data
              (e.g.  the  time  to wait for a response to a Class 2/2.0 AT+FDR
              command).

       ModemRaiseATCommands
              Indicates whether or not all configuration AT commands  for  the
              modem   should  be  raised  to  upper-case  automatically.   The
              standard is for all upper-case to be used in  AT  commands,  and
              indeed,  some  rare  modems  have been known to malfunction with
              lower-case commands.  However, sometimes  an  administrator  may
              want  to  use lower-case commands in a rare condition such as to
              work around modem blacklisting of dialed numbers.

       ModemRate
              The baud rate to use for DCE-DTE communication.  This value  may
              be one of: 115200, 76800, 57600, 38400, 19200, 9600, 4800, 2400,
              1200.  The default value is 19200 because many modems  lock  the
              rate  at  19200  when sending or receiving facsimile.  Note that
              not all values  are  supported  by  all  operating  systems  and
              modems;  consult stty(1) for the available rates on your system.

       ModemReadyCmds
              A string of commands to issue  to  the  modem  during  reception
              initialization.   This  string  is  sent  to the modem after the
              standard set of  configuration  commands  required  by  the  fax
              server.   This  is  done,  for example, to un-busy a DID line so
              that calls can come through.

       ModemRecvFillOrder
              The bit order to expect for received facsimile data.  This value
              may  be  either  LSB2MSB  when  bits  are  ordered  from  least-
              significant-bit  to  most-significant-bit  (as  in   the   CCITT
              specification)  or  MSB2LSB when bits are ordered in the reverse
              direction.  According to the various specifications  all  modems
              should  return  data  in  LSB2MSB  order.   However most Class 2
              modems  (except  maybe   only   Multitech)   use   MSB2LSB   for
              compatibility   with   modems  that  were  built  with  Rockwell
              hardware/firmware that included a bug that was too widespread to
              correct.

              If this parameter is not set, then it is autodetected and set to
              LSB2MSB for Class 1 and Class 2.0 modems and  MSB2LSB  for  non-
              Multitech  Class  2  modems.  However this may be wrong for your
              modem, so you will have to specify this parameter explicitly.

       ModemRecvSuccessCmd
              A string of commands to issue to the modem  after  a  successful
              receive session before the call is disconnected.

       ModemResetCmds
              A   string   of   commands   to   issue   to  the  modem  during
              initialization.  This string is sent to  the  modem  before  the
              standard  set  of  configuration  commands  required  by the fax
              server.  Note that these  commands  should  not  include  normal
              reset commands that are specified through other parameters.  For
              example, commands to  setup  flow  control,  DCD  handling,  DTR
              handling,  etc.  should  be  specified  through  the appropriate
              configuration parameters and not  through  this  parameter.   In
              addition  the soft reset command (usually ‘‘ATZ’’) should not be
              included  in  this  string;  the  servers  issue  this   command
              explicitly.

       ModemResetDelay
              The  time, in milliseconds, to pause after setting DTR ON, while
              resetting a modem.  DTR ON does not respond with ‘‘OK’’, so this
              parameter  should  be  long enough to allow the modem time to be
              ready for ModemSoftResetCmd successively.

       ModemResultCodesCmd
              The command to enable result codes.

       ModemRevQueryCmd
              The command to send to the modem  to  get  a  firmware  revision
              identification string.  If this parameter is not set, then it is
              initialized  to  ‘‘AT+FREV?’’  for  Class  2   modems,   or   to
              ‘‘AT+FMR?’’  for Class 2.0 modems.  If the parameter begins with
              a ‘‘!’’, then the remainder of the string is  taken  to  be  the
              identification string and no command is issued to the modem.

       ModemSendBeginCmd
              The  command  to  send  to  the  modem upon establishing carrier
              during a transmit  operation.   This  parameter  is  useful  for
              systems  that  are  incapable  of enabling hardware flow control
              without DCD asserted.

       ModemSendFillOrder
              The bit order the modem expects for transmitted facsimile  data.
              This   value   may  be  either  LSB2MSB  or  MSB2LSB  (see  also
              ModemRecvFillOrder  above.)    Virtually   all   modems   expect
              transmitted facsimile data in LSB2MSB bit order.

       ModemSetVolumeCmd
              The  commands  to  use  to  set the modem speaker volume levels.
              There should be five whitespace-separated commands, one each for
              setting  the  volume to ‘‘Off’’, ‘‘Quiet’’, ‘‘Low’’, ‘‘Medium’’,
              and ‘‘High’’;  the  default  is  ‘‘"ATM0  ATL0M1  ATL1M1  ATL2M1
              ATL3M1"’’.  See also SpeakerVolume.

       ModemSetupAACmd
              The  command  to  setup  adaptive answer support in the modem-if
              available.  Adaptive answer is the term used for the ability  to
              distinguish  between  calls  from  facsimile,  voice,  and  data
              sources.  Note that this string is the last  command  issued  by
              the  device  drivers during setup, so the command string may, if
              necessary, switch to a different operating mode  (e.g.  on  some
              Rockwell-based  modems it is necessary to issue the ‘‘AT+FAA=1’’
              command in Class 0).

       ModemSetupDCDCmd
              The  command  to  setup  DCD  handling.   On  most  systems  the
              facsimile  server  will enable the CLOCAL flag on the tty device
              to which the modem is connected.  This should  insure  that  the
              system  does  not  close an open file descriptor associated with
              the modem if carrier is dropped.  Thus,  for  most  systems  and
              modems ModemSetupDCDCmd should setup DCD to reflect carrier.

       ModemSetupDTRCmd
              The  command  to  setup  DTR handling so that the modem is reset
              when the DTR signal is  lowered  by  the  host.   The  facsimile
              server  uses this facility to insure that modems are not left in
              a ‘‘locked up’’ state.

       ModemSoftFlowCmd
              The command to setup software (XON/XOFF)  flow  control  between
              DTE and DCE.

       ModemSoftResetCmd
              The command to force a soft reset of the modem.

       ModemSoftResetCmdDelay
              The  time,  in  milliseconds,  to  pause  after receiving the OK
              following ModemSoftResetCmd before any further commands are sent
              to the modem.

       ModemSoftRTFCC
              Whether   or   not   to  enable  software-driven  Real-Time  Fax
              Compression Conversion.  RTFCC allows  HylaFAX  to  convert  the
              image  compression  between  MH MR and MMR formats regardless of
              how faxq formatted the image file.  Note that when using  RTFCC,
              the  compression  format  of  the file will be ignored, thus the
              ‘‘-1’’, ‘‘-2’’, and ‘‘-3’’  options  for  sendfax,  ps2fax,  and
              others  will only influence how the document is prepared by faxq
              and will not influence the actual negotiated session parameters.
              Class2RTFCC takes precedence over ModemSoftRTFCC and if both are
              enabled, then software-driven RTFCC will  not  be  performed  in
              favor of the firmware-driven RTFCC.

       ModemType
              This  parameter must be set to one of: ‘‘Class2’’, ‘‘Class2.0’’,
              or ‘‘Class1’’; to indicate that the modem is a Class  2-,  Class
              2.0-,  or  Class 1-style modem, respectively.  If this parameter
              is not set, then it is autodetected and  the  highest  supported
              fax class is used.

       ModemVerboseResultsCmd
              The  command  to  enable  verbose, as opposed to numeric, result
              codes.

       ModemWaitForConnect
              If enabled, the facsimile server will not consider a  connection
              established  when answering an incoming call until a ‘‘CONNECT’’
              status string is received.  This is useful mainly  for  Rockwell
              RC32ACL-based  modems  that  send  ‘‘FAX’’  and  ‘‘DATA’’ status
              messages before sending ‘‘CONNECT’’.

       ModemWaitTimeCmd
              The command to set the number of seconds to wait for  a  carrier
              signal when placing a call or answering the phone.

T.30 PROTOCOL CONFIGURATION PARAMETERS

       The  following parameters apply to the implementation of the CCITT T.30
       facsimile protocol in the Class 1 device driver.  They  should  not  be
       changed without full understanding of the operation of the server.

       FaxT1Timer
              The  value  of the T1 timer in milliseconds.  This timer is used
              to time  out  the  initial  session  contact;  i.e.  receipt  of
              DIS/DCS.

       FaxT2Timer
              The  value  of the T2 timer in milliseconds.  This timer is used
              to time out receiving responses and commands.

       FaxT4Timer
              The value of the T4 timer in milliseconds.  This timer  is  used
              to  time  out the reception of HDLC frames and, usually, trigger
              frame retransmissions.

CLASS 1 MODEM CONFIGURATION PARAMETERS

       The following parameters are specific to  the  configuration  of  Class
       1-style modems; they should not be changed lightly:

       Class1Cmd
              The command to set the modem into Class 1 operation.

       Class1AdaptRecvCmd
              The  command  used to enable adaptive reception support (usually
              ‘‘AT+FAR=1’’).  This feature is new in  T.31,  and  many  modems
              will  not  support  it.   This  feature may reduce the number of
              reception  failures  due  to  errors  cascading  from   +FCERROR
              messages.

       Class1ColorJPEGSupport
              Whether or not to enable support for T.30-E full-color facsimile
              with JPEG  compression.   Enabling  this  automatically  enables
              Class1GreyJPEGSupport.

       Class1EnableV34Cmd
              The command to enable V.34-fax support with at least the desired
              maximum primary channel rate.

       Class1ECMSupport
              Whether or not to support T.30-A error correction protocol.  Use
              of  ECM  will  require  64 kilobytes of free memory per modem in
              active use.

       Class1PersistentECM
              Whether or not to continue to retransmit and allow  to  continue
              to  receive  image data in ECM protocol which is not accepted as
              valid after four successive attempts.

       Class1ECMFrameSize
              The size in  bytes  of  image  frames  to  transmit  during  ECM
              protocol.   This  setting  will  also  indicate  a preference in
              receive sessions.  The only acceptable values are 64 and 256.  A
              setting  of  64  may be useful on high-load systems and possibly
              environments with extremely poor line quality.

       Class1ExtendedRes
              Whether or not to support  resolutions  other  than  normal  and
              fine.  This option has been deprecated by Class1Resolutions.

       Class1FrameOverhead
              The  number  of extraneous bytes in HDLC frames sent to the host
              in response to an ‘‘AT+FRH’’ command.  For modems that  properly
              implement  the  Class  1 interface, this number should be 4 (the
              default).

       Class1GreyJPEGSupport
              Whether or not to enable support for T.30-E greyscale  facsimile
              with    JPEG   compression.    This   is   always   enabled   if
              Class1ColorJPEGSupport is enabled.

       Class1HookSensitivity
              The number of times to  ignore  on-hook  detections  and  merely
              treat them as command or modem errors.

       Class1JBIGSupport
              Whether  or  not to enable support for T.85 monochrome facsimile
              with JBIG compression.  Options are ‘‘true’’ for support in both
              sending  and  receiving,  ‘‘false’’ for no support, ‘‘send’’ for
              support only in sending, and ‘‘receive’’  for  support  only  in
              receiving.   If,  during  the  build  process  a compatible JBIG
              library was found then send support is enabled by default.   If,
              during  the  build  process  the TIFF tools are found to support
              JBIG then receive support is enabled by default.

       Class1HasRHConnectBug
              A Class 1 modem should only report CONNECT after  AT+FRH=3  when
              V.21   HDLC   data  is  detected.   However,  some  modems  will
              incorrectly report CONNECT after AT+FRH=3 whenever  any  carrier
              is present. In such cases Class1HasRHConnectBug should be set to
              ‘‘true’’.

       Class1HFLOCmd
              The command to setup hardware (RTS/CTS) flow control between DTE
              and  DCE  when  operating  in  Class  1.  This command is issued
              immediately after sending the Class1Cmd to switch the  modem  to
              Class 1 operation.

       Class1MRSupport
              Whether  or  not  to enable support for two-dimensional Modified
              Read (MR) image data format compression.

       Class1MMRSupport
              Whether or not to enable support  for  two-dimensional  Modified
              Modified  Read  (MMR)  image data format compression.  Note that
              MMR support requires also ECM support to be enabled.

       Class1NFLOCmd
              The command to setup no flow control between DTE  and  DCE  when
              operating  in Class 1.  This command is issued immediately after
              sending the Class1Cmd to switch the modem to Class 1  operation.

       Class1PageLengthSupport
              The  coded  value  for page lengths supported by the modem.  The
              only correct values and  meanings  are  these:  ‘‘1’’,  A4  page
              length; ‘‘3’’, both A4 and B4 page length; ‘‘7’’, unlimited page
              length.

       Class1PageWidthSupport
              The coded value for page widths supported  by  the  modem.   The
              only  correct  values  and  meanings  are  these: ‘‘1’’, A4 page
              width; ‘‘3’’, both A4 and B4 page width; ‘‘7’’, all of  A4,  B4,
              and A3 page widths.

       Class1PPMWaitCmd
              The  command  used to stop and wait before sending the post page
              message, except before sending  EOP,  when  Class1EOPWaitCmd  is
              used  instead.   We  must ensure that the high-speed carrier has
              stopped completely.  According to T.30, Chapter 5, Note 4,  this
              delay should be 75 +/- 20 ms.

       Class1ResponseWaitCmd
              The  command  used  to  stop  and wait after sending TCF, before
              attempting to receive a training response from the remote.   Set
              this  to  ‘‘AT+FRS=1’’  if  you  experience ‘‘DIS/DTC received 3
              times’’ errors.

       Class1Resolutions
              A bitmapped (bit-or’d) value indicating the  resolutions  to  be
              supported  during  facsimile  operation.  Individual resolutions
              follow Table 21/T.32 and are defined as follows:
              Bit              Description
              0 (0x00)         R8 x 3.85 l/mm, Normal
              1 (0x01)         R8 x 7.7 l/mm, Fine
              2 (0x02)         R8 x 15.4 l/mm, Superfine
              4 (0x04)         R16 x 15.4 l/mm, Hyperfine
              8 (0x08)         200 dpi x 100 l/inch
              16 (0x10)        200 dpi x 200 l/inch
              32 (0x20)        200 dpi x 400 l/inch
              64 (0x40)        300 dpi x 300 l/inch
              Thus, a value of 3 would indicate support for normal, fine,  and
              superfine resolutions.

       Class1RMQueryCmd
              The  command  to  send to the modem to get the list of supported
              reception bit-rates.  If the parameter begins with a ‘‘!’’, then
              the  remainder  of  the string is taken to be the modem response
              and no command is issued to the modem.

       Class1TCFWaitCmd
              The command used to stop and wait before sending TCF, similar to
              Class1PPMWaitCmd.   According  to  T.30, Chapter 5, Note 3, this
              delay should be 75 +/- 20 ms.

       Class1TMQueryCmd
              The command to send to the modem to get the  list  of  supported
              transmission  bit-rates.   If the parameter begins with a ‘‘!’’,
              then the remainder of the  string  is  taken  to  be  the  modem
              response and no command is issued to the modem.

       Class1EOPWaitCmd
              The  command  used to stop and wait before sending the post page
              message similar  to  Class1PPMWaitCmd.   We  allow  a  different
              setting  in  the  case of EOP, however, because empirically some
              machines may need more time.

       Class1ModemHasDLEBug
              Used to indicate that the modem does not correctly duplicate DLE
              characters in the V.21 communication to the DTE.

       Class1MsgRecvHackCmd
              If  receive  failures  occur due to +FCERROR just prior to image
              data reception, setting  Class1MsgRecvHackCmd  to  AT+FRS=1  may
              help.

       Class1RecvAbortOK
              The  time,  in  milliseconds,  to wait for an ‘‘OK’’ result code
              from  the  modem  after   aborting   an   HDLC   frame   receive
              (‘‘AT+FRH=3’’).   If  this  number  is  zero,  then the modem is
              assumed to not correctly  implement  aborting  and  instead  the
              driver  will wait 200ms, flush any input, and then send ‘‘AT\n’’
              and wait 100ms for an ‘‘OK’’ result.

       Class1RecvIdentTimer
              The time, in milliseconds, to  wait  for  an  initial  DCS  when
              receiving a facsimile.  CCITT recommendation T.30 specifies this
              as the value of  the  T1  timer.   However,  adaptive  answering
              schemes  such  as  that described above under the AdaptiveAnswer
              parameter may require that this timer be shortened.

       Class1RMPersistence
              The number of times that an attempt to  receive  the  high-speed
              data  carrier  should be made, resulting in +FCERROR, before the
              low-speed message carrier reception is attempted.   Some  modems
              are  quick  to  (perhaps  incorrectly)  return +FCERROR, and for
              those modems a value of 2 or 3 should be used.  For modems  that
              are  not  quick to return +FCERROR, a value of 1 should be used.
              Proper tuning of this can provide a type of "adaptive  reception
              control"  for  modems  that  accurately  return +FCERROR without
              supporting Class1AdaptRecvCmd.  For those  modems  that  support
              Class1AdaptRecvCmd,  Class1RMPersistence  should probably not be
              set at 1, although +FCERROR should almost never occur with  such
              modems.

              If  the  modem  does  not  support  the reporting of +FCERROR or
              adaptive  reception  control,  then  Class1RMPersistence  should
              probably  be  set at 0, which causes the timeout looking for the
              high-speed data carrier to be  shortened,  thus  increasing  the
              likelihood   of   recovery  from  any  dissynchronization.  When
              Class1RMPersistence is other than  0  it  is  assumed  that  the
              +FCERROR  reporting  or  Class1AdaptRecvCmd  is  functional  and
              therefore the timeout looking for the high-speed data carrier is
              lengthened.

       Class1SwitchingCmd
              The command used to ensure that the sending facsimile device has
              turned off its modulator (i.e. loss-of-carrier)  as  recommended
              by T.31: Appendix II.1.

       Class1SFLOCmd
              The  command  to  setup software (XON/XOFF) flow control between
              DTE and DCE when operating in Class 1.  This command  is  issued
              immediately  after  sending the Class1Cmd to switch the modem to
              Class 1 operation.

       Class1TCFMaxNonZero
              The maximum percentage of non-zero data bytes  permitted  in  an
              acceptable received TCF.  Note that this number does not include
              any leading non-zero  data  in  the  received  data.   See  also
              Class1TCFMinRun.

       Class1TCFMinRun
              The  duration,  in milliseconds, of the minimum run of zero data
              in an acceptable received TCF.  This value should  be  specified
              according  to  a  1.5  second transmission of zero data (i.e. it
              should be between 0 and 1500).  See also Class1TCFMaxNonZero and
              Class1TCFMinRunECMMod.

       Class1TCFMinRunECMMod
              The  factor  by  which Class1TCFMinRun should be modified in the
              case of an ECM session.  As ECM protocol allows  retransmissions
              it is commonly faster to accept a lesser-quality data stream and
              the  subsequent  retransmisisons  than  it  is  to   allow   the
              communication  speed  to  slow  down (where the demodulation may
              still not produce an ideal data stream, anyway).

       Class1TCFRecvHackCmd
              If receive failures occur due to +FCERROR just prior to TCF data
              reception, setting Class1TCFRecvHackCmd to AT+FRS=1 may help.

       Class1TCFRecvTimeout
              The  maximum  time  to wait, in milliseconds, for the first byte
              and again for the entirety of the Training Check  (TCF)  message
              data that is received during the training phase of the facsimile
              reception protocol.

       Class1TMConnectDelay
              The time, in milliseconds,  to  delay  after  receiving  CONNECT
              following  +FTM  before sending image data.  T.31 8.3.3 requires
              the modem to respond with CONNECT before the modulation training
              pattern.    If   transmission   begins  before  the  remote  has
              successfully completed its own modulation training pattern  then
              data,  especially during TCF, could be lost.  Many modems do not
              follow T.31 in this  regard,  and  thus  the  default  is  zero;
              however  its use with such modems would likely have a negligible
              effect.

       Class1ValidateV21Frames
              Whether or not to use the FCS bits of received V.21 HDLC  frames
              to  check the validity of the frame itself.  Most Class 1 modems
              perform this check independently  (per  T.31  7.4)  and  do  not
              require this feature to be enabled.

CLASS 2 AND 2.0 MODEM CONFIGURATION PARAMETERS

       The  following parameters are specific to the configuration of Class 2-
       and Class 2.0-style modems:

       Class2Cmd
              The command to set the modem into Class 2/2.0 operation.

       Class2AbortCmd
              The command to use to abort an established session.  After using
              this  command  to  abort  a  session, the fax software will send
              ModemOnHookCmd and then reset the modem by dropping DTR .

       Class2APCmd
              A largely unused option for modems  supporting  ITU-T.32,  Class
              2.1,  standards.   This  command would be used to enable sending
              and receiving SUB, SEP, and PWD frames.

       Class2APQueryCmd
              A largely unused option for modems  supporting  ITU-T.32,  Class
              2.1,  standards.   This  command  would  be  used  to  query the
              capabilities of sending and receiving SUB, SEP, and PWD  frames.
              The value ‘‘none’’ may be used if the modem does not support any
              Class2APQueryCmd.

       Class2BORCmd
              The command  to  setup  the  bit  order  of  sent  and  received
              facsimile  data.   Usually  the command ‘‘AT+FBOR=0’’ is used so
              that data is sent and received in direct  bit  order  (LSB2MSB).
              Some  modems,  such  as the Everex 24/96D, must use reversed bit
              order for Phase B and D data  exchanges  to  avoid  a  bug  that
              results  in  garbage  data  being  placed  in the padding of EOL
              codes.  The bit order specified by this command must  correspond
              to the settings of the ModemSendFillOrder and ModemRecvFillOrder
              parameters.

       Class2BUGCmd
              The command to use to enable or  disable  the  tracing  of  HDLC
              frames sent and received by the modem.  This tracing information
              should be returned to the host in ‘‘+FHR:’’ and ‘‘+FHT:’’ status
              strings.   Note  that  many  Class  2 modems do not support this
              facility, which is largely used for  diagnostic  purposes.   The
              value  ‘‘none’’  may  be  used if the modem does not support any
              Class2BUGCmd.

       Class2CIGCmd
              The command used to set a polling identifier.   This  string  is
              inserted into the format ‘‘%s="<id>"’’.

       Class2CQCmd
              The  command  to  use  to  set  up  parameters  for copy quality
              checking.   For  example,  for  an  Everex  24/96D  modem   this
              parameter           might           be           set          to
              ‘‘AT+FCQ=1\nAT+FBADMUL=20\nAT+FBADLIN=10’’.  Class2CQCmd  should
              be  configured  to  set-up  all  available copy quality services
              available per Class2CQQueryCmd.  To disable  features  that  are
              available, configure Class2CQQueryCmd with a ‘‘!’’, and then set
              Class2CQCmd accordingly.

       Class2CQQueryCmd
              The command to send  to  the  modem  to  get  the  copy  quality
              capabilities string.  If the parameter begins with a ‘‘!’’, then
              the remainder of the string is  taken  to  be  the  capabilities
              string  and  no command is issued to the modem; this can be used
              together with the Class2CQCmd to force copy quality checking  to
              be  done  in  the  server  instead  of  in  the modem.  See also
              PercentGoodLines and MaxConsecutiveBadLines for parameters  used
              to do server copy quality checking.  If copy quality checking is
              configured to be done by the modem then it is not  done  by  the
              server.

       Class2CRCmd
              The command to use to enable the reception of facsimile.

       Class2DCCCmd
              The  command  used  to  set  modem capabilities.  This string is
              inserted into the format ‘‘%s=vr,br,wd,ln,df,ec,bf,st’’.

       Class2DCCQueryCmd
              The command to  send  to  the  modem  to  get  the  Class  2/2.0
              capabilities.   If  the  parameter begins with a ‘‘!’’, then the
              remainder of the string is taken to be the  capabilities  string
              and no command is issued to the modem.

       Class2DDISCmd
              The  command  to  set  session  parameters before dialing.  This
              string       is       inserted       into       the       format
              ‘‘%s=vr,br,wd,ln,df,ec,bf,st’’.   Setting this parameter enables
              support for Class 2 modems that do not  properly  implement  the
              ‘‘AT+FDIS’’  command  by  setting  up  session parameters before
              dialing the telephone.

       Class2DISCmd
              The command used to set the current  session  parameters.   This
              string       is       inserted       into       the       format
              ‘‘%s=vr,br,wd,ln,df,ec,bf,st’’.

       Class2ECMType
              The interpretation of the EC parameter in the modem DCC response
              varies  between  the  Class  2,  ‘‘2’’,  and Class 2.0, ‘‘2.0’’,
              specifications.   This  configuration   parameter   allows   the
              administrator  to  specify which type to use.  The corresponding
              specification type is used by default.

       Class2HexNSF
              Whether or not to parse the NSF strings reported  by  the  modem
              using  hexadecimal  values.   By  default,  they  are  parsed as
              hexadecimal values.

       Class2HFLOCmd
              The command to setup hardware (RTS/CTS) flow control between DTE
              and  DCE  when operating in Class 2/2.0.  This command is issued
              immediately after sending the Class2Cmd to switch the  modem  to
              Class  2/2.0  operation.  For Class 2.0 operation the default is
              ‘‘AT+FLO=2’’.

       Class2JPEGSupport
              Whether or not to enable and utilize the JPEG support  found  in
              the modem.

       Class2LIDCmd
              The  command  used  to  set  the  local identifier string.  This
              string is inserted into the format ‘‘%s="<id>"’’

       Class2MINSPCmd
              The command used to set  the  minimum  acceptable  speed  to  be
              negotiated  for transmitting page data.  This string is inserted
              into the format ‘‘%s=<speed>’’

       Class2NFLOCmd
              The command to setup no flow control between DTE  and  DCE  when
              operating  in  Class  2/2.0.  This command is issued immediately
              after sending the Class2Cmd to  switch  the  modem  to  Class  2
              operation.  For Class 2.0 operation the default is ‘‘AT+FLO=0’’.

       Class2NRCmd
              (Class 2.0  only)  The  command  to  setup  negotiation  message
              reporting.   For  the  correct operation of the Class 2.0 driver
              this command must enable the reporting of: receiver  parameters,
              transmitter  parameters, and ID strings.  It is not necessary to
              enable reporting of non-standard frames for correct operation of
              the Class 2.0 driver.

       Class2PACmd
              A  largely  unused  option for modems supporting ITU-T.32, Class
              2.1, standards.  This command  would  be  used  to  set  up  the
              polling address string enabled by the Class2APCmd.

       Class2PHCTOCmd
              The  command  to  use  to  set the Phase C timeout parameter (in
              seconds).  The value ‘‘none’’ may be used if the modem does  not
              support any Class2PHCTOCmd.

       Class2PIECmd
              (Class  2.0  only)  The  command  to  use  to  control procedure
              interrupt handling.  Procedure  interrupts  should  be  disabled
              because  HylaFAX  does  not  provide a mechanism for dispatching
              procedure interrupts to an administrator.

       Class2PTSCmd
              The command to use to set the received page status  code.   When
              copy  quality  checking is done in the host, this command may be
              used to control the post-page response delivered to the  sender.
              Beware  that  some modems do not properly implement this command
              in which case the server should be configured  to  not  do  copy
              quality      check:     see     the     PercentGoodLines     and
              MaxConsecutiveBadLines parameters to understand  how  to  defeat
              copy quality checking.

       Class2PTSQueryCmd
              The command to use to query the received page status code.  This
              command may be used to determine the post-page response returned
              from  the  receiver.   Beware  that  some modems do not properly
              implement this command in which case this setting should be  set
              to ‘‘none’’.

       Class2PWCmd
              A  largely  unused  option for modems supporting ITU-T.32, Class
              2.1, standards.  This command  would  be  used  to  set  up  the
              password string enabled by the Class2APCmd.

       Class2RecvDataTrigger
              The  character  to send to the modem to trigger the transmission
              of received data from the modem to the host.  This character  is
              specified to be DC1 (octal 21) in the draft specification 2388-A
              and DC2 (octal 22) in the 2388-B specification.   Most  Class  2
              modems accept DC1 or both DC1 and DC2.  Some modems however only
              accept DC2.  Note that string parameters may use C-style  escape
              sequences,   so   DC2,   for  example,  would  be  specified  as
              ‘‘"\022"’’.

       Class2RELCmd
              The command to use to enable the delivery  of  byte-aligned  EOL
              codes in received facsimile.  If this parameter is defined, then
              received facsimile data will be  marked  to  indicate  that  EOL
              codes  are  byte-aligned;  otherwise  they will be marked as not
              (necessarily) having byte-aligned codes.

       Class2RTFCC
              Whether or not to enable MultiTech’s Real-Time  Fax  Compression
              Conversion  which  is  available in later firmware revisions for
              the MT5634ZBA-V92, MT5634ZPX-PCI-V92, and other  models.   RTFCC
              allows  HylaFAX  to  convert the image compression between MH MR
              and MMR formats regardless of how faxq formatted the image file.
              If  RTFCC  is available with your firmware, then the response to
              ‘‘AT+FFC=?’’ is non-zero.   Note  that  when  using  RTFCC,  the
              compression format of the file will be ignored, thus the ‘‘-1’’,
              ‘‘-2’’, and ‘‘-3’’ options for sendfax, ps2fax, and others  will
              not influence the actual negotiated session parameters.

       Class2SACmd
              A  largely  unused  option for modems supporting ITU-T.32, Class
              2.1, standards.  This command  would  be  used  to  set  up  the
              destination subaddress string enabled by the Class2APCmd.

       Class2SendRTC
              Whether or not to append an explicit ‘‘Return To Control’’ (RTC)
              signal to the page data when  transmitting.   The  Class  2  and
              Class  2.0 specs (i.e. SP-2388-A and TIA/EIA-592) state that the
              modem will append RTC when it  receives  the  post-page  message
              command  from  the  host; this parameter is provided in case the
              modem does not correctly implement this.

       Class2SFLOCmd
              The command to setup software (XON/XOFF)  flow  control  between
              DTE  and  DCE  when  operating  in Class 2/2.0.  This command is
              issued immediately after sending the  Class2Cmd  to  switch  the
              modem  to  Class  2/2.0  operation.  For Class 2.0 operation the
              default is ‘‘AT+FLO=1’’.

       Class2SPLCmd
              The command to use to  enable  a  polling  request.   The  value
              ‘‘none’’  may  be  used  if  the  modem  does  not  support  any
              Class2SPLCmd.

       Class2TBCCmd
              The command to use to enable stream-mode  communication  between
              the host and modem.  The value ‘‘none’’ may be used if the modem
              does not support any Class2TBCCmd.

       Class2UseLineCount
              Whether or not to use the line count reported to HylaFAX by  the
              modem firmware decoder.

       Class2UseHex
              Whether or not to parse the capabilities strings reported by the
              modem using hexadecimal values.  By default, they are parsed  as
              decimal values.

       Class2XmitWaitForXON
              Whether  or  not  to  wait  for  an XON character from the modem
              before sending facsimile data to  the  modem  for  transmission.
              Note  that  this is only relevant for modems that conform to the
              Class 2 spec (i.e.  SP-2388-A).   The  Class  2.0  specification
              states   that  the  host  may  transmit  data  immediately  upon
              receiving CONNECT and that no XON character will be sent to  the
              host.

PAGER-RELATED CONFIGURATION PARAMETERS

       The   following  parameters  are  specific  to  the  configuration  and
       operation of the IXO/TAP and UCP support for sending pager messages and
       GSM  SM. Parameter not used for UCP are marked with ‘‘(IXO/TAP only)’’.

       PagerSetupCmds
              The commands to send to a modem to prepare the modem for a  call
              to  pager  service  provider.   Typically  these  commands place
              direct the modem to communicate with the service provider at 300
              bps  using  the  V.21  protocol.   Per-service  provider command
              strings can be setup in the info database; see  hylafax-info(5).

       PagerMaxMsgLength
              The  maximum  length  for a pager text message.  Messages longer
              than this number are truncated.   Per-service  provider  message
              lengths  can be setup in the info database; see hylafax-info(5).

       IXOService
              (IXO/TAP only) The service identification string transmitted  as
              part of the IXO/TAP protocol.

       IXODeviceID
              (IXO/TAP   only)   The  terminal  device  identification  string
              transmitted as part of the IXO/TAP protocol.

       IXOMaxUnknown
              The  maximum  number  of  unrecognized  messages  that  will  be
              accepted  at  various  stages of the IXO/TAP protocol before the
              sender will abort and hangup the phone.

       IXOIDProbe
              (IXO/TAP only) The time, in seconds, between  sending  a  ‘‘\r’’
              during  the  initial  ID  recognition  sequence  of  the IXO/TAP
              protocol.

       IXOIDTimeout
              (IXO/TAP only) The maximum time, in seconds,  to  wait  for  the
              initial ID response from the service provider.

       IXOLoginRetries
              (IXO/TAP  only)  The  maximum  number  of attempts to login to a
              service provider.

       IXOLoginTimeout
              (IXO/TAP only) The maximum time, in seconds, to wait to complete
              the login procedure.

       IXOGATimeout
              (IXO/TAP  only)  The maximum time, in seconds, to wait for a Go-
              Ahead message from the service provider.

       IXOXmitRetries

              in a single call.

       IXOXmitTimeout
              The maximum time, in seconds, to try transmitting a text message
              block.

       IXOAckTimeout
              (IXO/TAP only) integer          30                      IXO: max
              time  to  wait  for  msg  block  ack (secs) The maximum time, in
              seconds,  to  wait  for  an  acknowledgement  to  a  transmitted
              message.

PROTOTYPE CONFIGURATION FILES

       Per-modem  configuration  files  are  typically  derived from prototype
       files that have been created for known modems.  These  prototype  files
       are kept in the config subdirectory and, by convention, have names that
       identify a brand or type of modem and the DTE-DCE flow  control  scheme
       the  prototype  files  configures.   The faxaddmodem(8) program that is
       used to configure a modem for use  with  HylaFAX  selects  a  prototype
       configuration  file  using  information  retrieved  from  the modem and
       comments embedded in the prototype  files.   For  Class  1  modems  the
       product  ID code returned by the command ‘‘ATI0’’ and the response from
       the command ‘‘ATI3’’ are used to select a prototype configuration file,
       while  for  Class  2  modems  the manufacturer and model as returned by
       ‘‘AT+FMFR?’’ and ‘‘AT+FMDL?’’, respectively, are used  (or  ‘‘AT+FMI?’’
       and ‘‘AT+FMM?’’ for Class 2.0 modems).

       A  Class  1  prototype  configuration  file  is  identified  for use by
       faxaddmodem by searching for a comment of the form:
       # CONFIG:CLASS1:144:.*:RTSCTS: Manufacturer=’AT&T’ Model=Dataport
       In this example ‘‘144’’ is the product ID code  for  an  AT&T  DataPort
       modem, ‘‘.*’’ is a regular expression matched against the result string
       returned by the ‘‘ATI3’’ command, and ‘‘RTSCTS’’ indicates the modem is
       configured  to  use  hardware  flow  control during fax operation.  The
       remainder of the line is evaluated by the sh(1) and used to specify the
       modem’s  manufacturer  and  model  (since  Class  1  modems do not have
       standard commands to query this information).

       Class  2  and  2.0  prototype  configuration  files  match  the  string
       ‘‘manufacturer-model-flowcontrol’’   against   a   sh(1)  glob  pattern
       specified in the configuration file, where manufacturer and  model  are
       the  strings  returned  by querying the modem and flowcontrol is either
       ‘‘RTSCTS’’ for hardware flow control or ‘‘XONXOFF’’ for  software  flow
       control.  For example:
       # CONFIG: CLASS2: ZyXEL*-RTSCTS
       # CONFIG: CLASS2.0: USRobotics*-XONXOFF
       are  configuration  comments  that  appear  in the prototype file for a
       ZyXEL 1496E with Class 2 support, and for a US Robotics  Courier  modem
       with Class 2.0 firmware.

       The faxaddmodem program merges server-specific configuration parameters
       into a prototype configuration according  to  comments  placed  in  the
       prototype  file.  All lines between ‘‘BEGIN-SERVER’’ and ‘‘END-SERVER’’
       comments  are  placed  with  the   appropriate   server   configuration
       parameters.    Note   that   this   means  modem-related  configuration
       parameters must be placed outside this area of the file.
