FAXMODEM(8C)							  FAXMODEM(8C)

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(8C) 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(8C) program.	faxmo‐
       dem  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(5F) 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(8C)
       script or manually communicate with the modem.  For a Class 2 modem the
       capabilities  are given in the response to the ``AT+FDCC=?'' query com‐
       mand 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 exam‐
       ple,
	      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 spec‐
		 ifies	vertical  resolution, br specifies bit rate, wd speci‐
		 fies 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 num‐
		 bers 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;  sup‐
		 ports	signalling rates 0-3 (2400 bps through 9600 bps); sup‐
		 ports 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	 sepa‐
		 rately with the -p and -P options.

       -p	 Specify  the modem is not capable of polling for remote docu‐
		 ments.

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

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

       -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/fax		      default spooling area
       /var/spool/fax/FIFO	      fifo for contacting faxq

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