       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 created 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 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 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

              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.


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

       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

              11     waiting for XON failed (rarely seen)

              12     transmitting  or  polling  page(s)   failed   (connection

       Very  detailed debug information is written to the log file.  It can be
       found  in  "/var/log/mgetty/fax/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 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.
