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

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

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

OPTIONS
       -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 noisy.

       -v     Give some progress report on stdout.

       -l <modem lines>
              Use the given modem lines. Multiple lines can be separated by ":".
              Example: sendfax -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 ``<filename>.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".

       -R <max tries>
              Sets the maximum number of attempts to transmit a given page,
              before sendfax gives up on this page.  Normally it's not needed to
              change this - the default is "(up to) 3 tries" and that works
              quite well for most environments.


CONFIG FILE
       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.


DIAGNOSTICS
       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.

       In Detail, the return codes are as follows:

              0      all pages have been transmitted successfully

              1      error on the sendfax command line

              2      cannot open fax device (e.g. due to locked modem)

              3      cannot initialize modem (e.g. modem switched off)

              4      dialup failed with BUSY

              5      dialup failed with NO DIALTONE

              10     dialup failed with ERROR or NO CARRIER (modem handshake
                     failed)

              11     waiting for XON failed (rarely seen)

              12     transmitting or polling page(s) failed (connection dropped)

       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.
