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.
JobReqError
The delay in seconds to wait before retrying a job whose dialing attempt failed
with a ``ERROR'' status result.
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.
JobRetryError
The number of times to redial a phone number after receiving a ``ERROR'' result
code 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
1 (0x00001) Server Operation queue management and general operation
2 (0x00002) FAX/IXO Protocol T.30 facsimile protocol or IXO/TAP protocol
4 (0x00004) Modem Operations modem hardware manipulation
8 (0x00008) Modem Communications commands passed between host and modem
16 (0x00010) Timeouts timer operations
32 (0x00020) Modem Capabilities modem capabilities
64 (0x00040) HDLC Frames binary T.30 HDLC frames
128 (0x00080) Binary Modem I/O binary communication between host and modem
256 (0x00100) Server State Transitionsserver program state transitions
512 (0x00200) Queue Management job queue management
1024 (0x00400) Copy Quality copy quality checking of received facsimile
2048 (0x00800) Job Management low-level job management
4096 (0x01000) IXO Protocol low-level IXO protocol
8192 (0x02000) Config File Parsing unknown configuration file parameters
16384 (0x04000) FIFO Messages inter-application messages
32768 (0x08000) Modem State Transitions modem state changes (down, busy, ready)
65536 (0x10000) Dial Rules dialstring rules parsing and execution
131072 (0x20000) Docq Changes document reference handling
262144 (0x40000) TIFF library any messages produced by the TIFF library
524288 (0x80000) ECM Frames binary T.30-A HDLC ECM frames
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
The maximum number of times to try sending a text message block 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.
