       faxmodem - dynamically add a modem to a HylaFAX server system


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


       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
              hyla% cu -l ttyf2

       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

       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


       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

       -P        Specify the modem is capable of polling for remote  documents

       -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.


       /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.
