faxq - HylaFAX queue manager process
/usr/sbin/faxq [ -D ] [ -q queue-dir ]
faxq is the central queueing agent for HylaFAX. One (and only one)
faxq process is normally running at all times. faxq is responsible for
scheduling, preparing, and initiating outbound facsimile jobs (and
potentially other types of jobs as well).
faxq may be run by itself to provide outbound-only services or it may
be run together with one or more faxgetty(8) processes, in which case
inbound services (e.g. receiving facsimile) are provided. When faxq is
run by itself the set of available modems must be specified using the
faxmodem(8) command. Each modem specified in this way is assumed to
exist and to be capable of use as a facsimile modem. When faxq is run
in conjunction with faxgetty processes, it is not necessary to use
faxmodem to specify modems; instead the programs communicate
information about the status and capabilities of each modem. The
latter setup provides a more robust and powerful system and is the
intended way for the software to operate.
faxq receives notification of outbound jobs to process from the
hfaxd(8) process that implements the server-side of the HylaFAX client-
server protocol. Notification is through messages sent to a FIFO
special file that faxq listens to. This file is also used by other
administrative programs such as faxquit(8).
Many aspects of faxq operation may be controlled through a
configuration file. This file is located in the spooler hierarchy in
the etc subdirectory and is named config (as opposed to the per-modem
configuration files named config.devid); consult hylafax-config(5) for
detailed information on this configuration file. Note that faxq
automatically re-reads its configuration file if it has been changed.
It is also possible to dynamically change configuration parameters in a
running process with the faxconfig(8) program. Beware however that
parameters changed in this way will be reset to the values specified in
the configuration file if the file is re-read.
-q dir The specified directory is treated as the spooling area. The
default spooling area, /var/spool/hylafax, is defined at the
time the software is built.
-D This option forces faxq to remain attached to the controlling
tty from which it was invoked. In normal operation faxq will
fork(2) and disassociate itself from the controlling tty.
This option is useful for debugging.

/var/spool/hylafax/etc/config configuration file
Consult hylafax-server(5) for a complete discussion of the structure
and content of the spooling area.
