pagesend - HylaFAX IXO/TAP and UCP transmit program
/usr/sbin/pagesend [ -l ] [ -p ] [ -c config ] -m device-ID qfile
pagesend is the program that implements the IXO/TAP and the UCP
transmission protocol for the HylaFAX system. pagesend is invoked by
the faxq scheduler process for each pager transmit attempt. pagesend
assumes that its current working directory is the top of the spooling
hierarchy and that a suitable modem device has been allocated for its
use. In normal use pagesend 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).
pagesend initializes the modem before attempting to transmit the pager
message using the information in the appropriate modem configuration
file. If the modem does not respond to this initialization, pagesend
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). pagesend 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.
Many aspects of pagesend 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 protocol which must be used for a specific service provider is
controled from the hylafax-info(5) file.
-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 pagesend. By default
pagesend 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 pagesend will raise its priority to reduce i/o
latency. This option is useful for debugging.
pagesend returns the new job status to faxq through the exit(2) return
value of the process: send_retry (0), retry job; send_failed (1), job
finished without success, send_done (2), job completed successfully,
send_reformat (3), job should be retried after documents are

and content of the spooling area.
