       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 log-
              ging, 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, what-
              soever. The modem must return "OK". If it returns "ERROR", send-
              fax  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 initial-
              ize 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 com-
              bination  with  faxrunqd’s policy routing option (see example in

       -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.con-
       fig. 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/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.gree- 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.
