       sendfax - send group 3 fax files (G3 files) with a class 2 faxmodem

       sendfax	[-p]  [-x<debuglevel>] [-v] [-l<modemlines>] [-m<initstring>] [-d<polldirectory>]
       [-C<modemclass>] [-S] [-n] [-r] [-D<dialprefix>] phone-number [g3file(s)]

       Send the named g3 fax files to the fax machine at "phone number". The g3 files can be cre-
       ated with pbm2g3(1) or GNU's GhostScript with the "digifax" driver.

       -p     Tells  sendfax  to try fax polling, that is, get any documents queued in the remote
	      fax machine for you (used for weather maps and the like)

       -x <debug level>
	      Use the given level of verbosity for logging - 0 means  no  logging,  5  is  really

       -v     Give some progress report on stdout.

       -l <modem lines>
	      Use  the given modem lines. Multiple lines can be separated by ":".  Example: send-
	      fax -l tty1a:tty2a

       -m <initstring>
	      Send an additional init string. This string is sent right  after	initializing  the
	      modem  and setting it into class 2 mode. You can use this to set the speaker value,
	      some special registers, whatsoever. The modem  must  return  "OK".  If  it  returns
	      "ERROR",	sendfax  prints  an error message and aborts.  You do not have to prepend
	      the "AT" prefix, but it won't do harm either.

       -d <directory>
	      Specify the directory where polled fax files should go to. Defaults to "."  for the
	      current directory. Unused if not polling a fax.

       -C <class>
	      Tells  sendfax  how  to  treat  the  modem.  Possible values for <class> are "auto"
	      (default, try to find out which fax command set the modem  supports),  "cls2"  (use
	      the  class  2  fax  command set, even if the modem claims to support class 2.0) and
	      "c2.0" (use the class 2.0 fax command set). Obviously, "data" (which is  valid  for
	      "mgetty -C ...") is not of much use here.

       -S     Assume  modem  connection  on  stdin, do not try to lock or initialize anything. To
	      take over existing connection (for interworking with vgetty et.al.) use with a dial
	      string  of  "T1"	(just  a  short  beep,	no phone number at all would confuse many
	      modems, a pulse dialed number may confuse the telco switch) and "-m ATX1"  (do  not
	      wait for dial tone).

       -n     Tells  sendfax  to  send	the fax pages in ``normal'' (204x98 dpi) mode. Default is
	      ``fine'' mode (204x196 dpi).

       -r     If this option is given, sendfax will rename all	the  fax  G3  files  to  ``<file-
	      name>.done''  after  successfully  sending  this.  This is intended to be used from
	      ``faxrunq'', to make sure that a partially-sended  fax  isn't  retransmitted  as	a
	      whole every time.

	      If  this option is set, sendfax will not (!) complain if not all files named on the
	      command line exist.

       -D <dial prefix>
	      Override the default (set by sendfax.config or in policy.h) for the 'ATxxx' command
	      to  dial	the  remote  number.   This is rarely used from the command line, but you
	      might want to use it in combination with	faxrunqd's  policy  routing  option  (see
	      example in faxrunqd.policy(5)).

       -M <max speed>
	      Sets  the maximum transmission (modem to modem) speed.  This is only needed in very
	      rare cases, because normally the modems negotiate the correct speed  automatically.
	      Example: "-M 7200".

       If  compiled  accordingly,  sendfax can read all its configuration from at run-time from a
       file, usually called /etc/mgetty+sendfax/sendfax.config.  See  the  documentation  in  the
       mgetty.info manual for details.

       sendfax	returns  an  error  code, according to the reason why the program terminated.  If
       everything went OK, sendfax returns 0. If ``harmless'' errors (didn't cost money) occured,
       an  error  code below 10 is returned. If a dial attempt failed after the remote end picked
       up (it will cost money), a return code of 10 or higher is returned.  See  mgetty.info  for
       more details.

       Very  detailed  debug  information  is  written	to  the  log  file.   It  can be found in
       "/var/log/sendfax.log". If it doesn't contain enough details, enhance the log  level  with
       the "-x" option to sendfax, e.g. "-x 5".

       Many  of the common problems and solutions are discussed in the mgetty manual and the FAQ.
       Please see the WWW page at http://alpha.greenie.net/mgetty/ for both.

       The standard for Group 3 fax is defined in CCITT Recommendation T.4.

       sendfax should be able to put a header on the page.

       sendfax should be able to read TIFF g3 input files.
