faxsend - HylaFAX facsimile transmit program
/usr/sbin/faxsend [ -l ] [ -p ] [ -c config ] -m device-ID qfile [qfile
faxsend is the program that implements the facsimile transmission
protocol for the HylaFAX system. faxsend is invoked by the faxq
scheduler process for each facsimile transmit attempt. faxsend assumes
that its current working directory is the top of the spooling
hierarchy, that a suitable modem device has been allocated for its use,
and that all documents to be sent are already converted to TIFF/F (TIFF
Class F) at the appropriate resolution and with an appropriate data
encoding. In normal use faxsend will inherit a lockfile for the modem
from the faxq process. The format of the job description file
specified on the command line is described in sendq(5).
faxsend initializes the modem before attempting to transmit the
facsimile using the information in the appropriate modem configuration
file. If the modem does not respond to this initialization, faxsend
will repeatedly try to initialize the modem. This behaviour is
required for send-only environments in which a faxgetty(8) process is
not run (and the modem would be known to be in a properly initialized
state). faxsend catches SIGINT and SIGTERM and cleans up any resources
it controls; this is the mechanism used by faxq to abort a job while it
is in progress.
Multiple fax jobs of documents with varying formatting may be sent in
one fax call by ``batching'' them by supplying faxsend with multiple
Many aspects of faxsend operation are controlled through a
configuration file. The configuration file is located in the spooler
hierarchy in the etc subdirectory and is named config.device-ID;
consult hylafax-config(5) for detailed information on the contents of
The following options are recognized:
-c config Treat config as a configuration parameter specification that
is interpreted after reading the per-device configuration
file. For example, ``-c sessiontracing:0x4f'' would set the
SessionTracing configuration parameter to ``0x4f'',
overriding any setting in the configuration file.
-m devID The device to use in processing the job. Note that this is a
device identifier and not the pathname of the tty special
file. A device identifier is formed from a device filename
by removing any leading ``/dev/'' and converting any ``/''
characters to ``_'' characters.
-l Do the UUCP lockfile protocol in faxsend. By default faxsend
assumes that it is invoked with the device already locked and
that it does not need to manage the lockfile.
-p Do not change the process priority when transmitting.
Normally faxsend will raise its priority to reduce i/o
latency. This option is useful for debugging.
faxsend returns the new job status to faxq through the returned value
in the associated qfile: send_retry, retry job; send_failed, job
finished without success, send_done, job completed successfully,
send_reformat, job should be retried after documents are reformatted.
