NAME

       faxmodem - dynamically add a modem to a HylaFAX server system

SYNOPSIS

       /usr/sbin/faxmodem  [  -q  queue-dir  ]  [ -c capabilities ] [ -p ] [ -P ] [ -u priority ]
       modem

DESCRIPTION

       faxmodem sends a message to the  HylaFAX  queuer  process  faxq(8)  telling  it  that  the
       specified  modem  is  ready  for  use and informing it about its fax-related capabilities.
       This is the mechanism by which modems are added in  a  send-only  configuration.   Once  a
       modem  has  been  configured its status can be reconfigured using the faxstate(8) program.
       faxmodem can also be used to alter the capabilities and usage  priority  of  a  previously
       configured modem.

       The  specified  modem  is either the terminal device name where the modem is attached or a
       HylaFAX device identifier (see hylafax-config(5) for information on  device  identifiers).
       Device  names  may  be  given  without a leading directory pathname; e.g. ttyf2 instead of
       /dev/ttyf2.

       To figure out the capabilities of a modem either use the probemodem(8) script or  manually
       communicate  with  the  modem.   For  a  Class  2  modem the capabilities are given in the
       response to the ``AT+FDCC=?'' query command and for a Class  2.0  modem  the  ``AT+FCC=?''
       command.  To check if a modem is capable of polled retrieval of documents use ``AT+FSP=?''
       for a Class 2.0 modem or ``AT+FSPL=?'' for a Class 2 modem; if ``1'' is indicated  in  the
       response then the modem supports polling.  For example,
              hyla% cu -l ttyf2
              Connected
              at+fclass=2.0
              OK
              at+fcc=?
              (0,1),(0-5),(0-2),(0-2),0,0,0,(0-7)
              OK
              at+fsp=?
              (0,1)
              OK

       In this case the modem would be added using the command:
              /usr/sbin/faxmodem -c '(0,1),(0-5),(0-2),(0-2),0,0,0,(0-7)' ttyf2

       (by default polling is assumed to be supported).

       Class  1  modems  require  a  different  technique.   The  host implements most of the fax
       protocol so all that is needed is to identify the  possible  signalling  rates  the  modem
       supports for transmitting; this is done with the ``AT+FTM=?'' command.  For example,
              hyla% cu -l ttyf2
              Connected
              at+fclass=1
              OK
              at+ftm=?
              24,48,72,73,74,96,97,98,121,122,145,146
              OK

       In  this  case  the modem supports 2400, 4800, 7200, 9600, 12200, and 14400 bps signalling
       rates so the modem would be added using:
              /usr/sbin/faxmodem -c '(0,1),(0-5),(0-2),(0-2),(0,1),0,0,(0-7)' ttyf2

OPTIONS

       The following options are available:

       -c        Specify the fax capabilities  using  the  syntax  defined  by  the  ``Class  2''
                 specification: ``(vr),(br),(wd),(ln),(df),(ec),(bf),(st)''.  where, vr specifies
                 vertical resolution,  br  specifies  bit  rate,  wd  specifies  page  width,  ln
                 specifies  page  length,  df  specifies  data  compression,  ec  specifies error
                 correction, bf specifies binary file transfer, and st specifies scan  time/line;
                 and  each of the above specifications is a range or list of numbers that defines
                 the exact capabilities of the modem.  For example, the default capabilities  are
                 ``(0,1),(0-3),(0-4),(0-2),(0),(0),(0),(0-7)''   which  specifies  the  modem  is
                 capable of sending and receiving both low and high resolution facsimile  with  a
                 variety  of  page  sizes;  supports  signalling rates 0-3 (2400 bps through 9600
                 bps); supports only 1D-encoded data compression;  and  does  not  support  error
                 correction  or  binary  file  transfer.   A  modem's  ability  to support polled
                 retrieval of facsimile is specified separately with the -p and -P options.

       -p        Specify the modem is not capable of polling for remote documents.

       -P        Specify the modem is capable of polling for remote documents (default).

       -q dir    Use a spooling area other than /var/spool/hylafax.

       -u priority
                 Assign the specified priority to the modem when scheduling it for outbound  use.
                 Modem  priorities  are  numbers in the range [0..255] with lower numbers meaning
                 higher priority.  Modems are initially assigned priority 255.

FILES

       /var/spool/hylafax                 default spooling area
       /var/spool/hylafax/FIFO            fifo for contacting faxq

       Consult hylafax-server(5) for a complete discussion of the structure and  content  of  the
       spooling area.
