NAME
       fax - make, send, receive, view or print a fax

SYNOPSIS
       fax help

       fax make [-l] file

       fax send [-l] [-v] { -m | number } filename...

       fax [ receive [-v] [ filename-prefix ] ]

       fax { print | view | rm } filename...

       fax { queue | status [t] |  start | stop }

       fax answer

OPTIONS
       -l	use low (96 line per inch) resolution

       -v	display verbose messages for debugging

       -m	the phone call has already been dialed manually

       The commands make, send, receive, view and queue may be abbreviated to their first charac-
       ters (e.g. ``fax q'').

       Assignments of the form VARIABLE=value may appear before the command name  to  temporarily
       change the values of most fax script variables (e.g. ``fax PAGE=A4 print letter.001'')

DESCRIPTION
       fax  provides  a simple user interface to the efax(1) and efix(1) programs.  It allows you
       to send text or Postscript files as faxes and receive, print or	preview  received  faxes.
       The fax help command prints a summary of the possible commands.

       To  send  a  fax,  the original files need to be converted from ASCII or Postscript into a
       particular bit-map format (TIFF with Group 3 encoding).	This can be done automatically by
       the fax send command or you can use the fax make command to do the conversion before send-
       ing the fax.  The conversion will create one file per page.  These  files  will	have  the
       name of the original file with the page number as an additional suffix.	For example, run-
       ning fax make doc.ps on the two-page postscript	file  doc.ps  would  generate  the  files
       doc.ps.001 and doc.ps.002.

       When  sending a fax with the fax send command you may dial the number manually and use the
       -m option or you may give the phone number on the command line.	The names of the files to
       be sent are given on the command line, usually by using wildcards.  For example, to send a
       multi-page fax consisting of the files doc.ps.001, doc.ps.002, and so on,  you  could  use
       the  command  fax send 555-1212 doc.ps.0* (if you had already run the fax make command) or
       simply fax send 555-1212 doc.ps.  If the number is busy	the  script  will  wait  and  try
       again.

       Use  the  fax  receive  command	to answer the phone and receive a fax.	If a file name is
       specified the received fax will be stored in files with the given file name plus an exten-
       sion  equal  to the page number.  If no options are given, the received fax will be stored
       in files having a name given by the date and time and an extension equal to the page  num-
       ber.   For  example,  a fax received beginning on July 4 at 3:05:20 pm will generate files
       0704150520.001, 0704150520.002, and so on.

       The fax print, fax view, and fax rm commands are used to print, preview or remove received
       fax files.  As with the send command the file names are usually given using wildcards.

       If  efax  has been installed for automatic fax reception you can use the fax queue command
       to check for files in the incoming spool directory.  The fax script can also be configured
       to  print  received  faxes or e-mail them as MIME attachments with type image/tiff-f.  For
       convenience the fax print, view and rm commands will first check for the  named	files  in
       this  spool  directory.	 The fax status command shows the status of the automatic receive
       process once, or every t seconds.  Privileged users can use the fax  stop  and  fax  start
       commands to stop and restart the fax reception daemon.

       The  fax  answer command is used for unattended reception of faxes.  It is normally placed
       in the inittab(5) or ttytab(5) file and is run automatically by init(8).

       The -v option displays verbose messages.

       Other features of the fax script are documented within the script:

       -  a directory that lets you specify recipients by name instead of number

       -  the fax new command to create a simple cover page and start up a text editor

       -  the fax makefont command converts a Postscript font to a bit-mapped  font  for  use  in
	  headers or text

RESOLUTION
       Faxes  can be created at low (98 lines per inch) or high (196 lpi) resolution.  Almost all
       fax machines will operate at either resolution.	By default files are created at high res-
       olution but you can use the optional -l argument to create files at low resolution.

SESSION LOGS
       The  modem  commands  and responses together with status and error messages are written to
       file.  If the fax is successfully sent or received the log file is removed.   Otherwise	a
       message	is  printed  showing  the  log	file  name.  Please send a copy of this file when
       reporting problems with efax.

FILES
       The fax script will `source' the optional shell	scripts  /etc/efax.rc,	~/.efaxrc  and/or
       ./.efaxrc before processing command-line arguments.  These files can be used to set script
       variables to custom values for a particular system, user and/or directory.

       The following files are created in the FAXDIR spool directory when automatic fax reception
       is  enabled (see the fax script).  DEV represents the name of the fax modem device file in
       /dev (e.g. cua1 for /dev/cua1).

       DEV.n	 the log file created by the fax answer daemon with process id n

       DEV.log	 contains collected log files for device DEV.  Log files  showing  a  termination
		 status  of  1	(device busy) or 4 (no response from modem) are not added to this
		 file.

       DEV.stop  created by the fax stop command to prevent the fax daemon from starting up.
