One faxgetty should be run for each facsimile modem on a machine. faxgetty is typically started by init(8). faxgetty can also be used with data-only modems; this may be desirable if some of the non-facsimile features are important, such as the support for screening calls according to Caller-ID information.
faxgetty listens to its facsimile modem for incoming calls and to a FIFO special file on which it accepts command directives from administrative commands such as faxanswer(8) and faxabort(8). faxgetty also catches SIGTERM and SIGINT signals; cleaning up any necessary resources before exiting.
Many aspects of faxgetty operation are controlled through a configuration file. In particular, for faxgetty to automatically invoke the getty(8) program to handle incoming data connections the GettyArgs parameter must be setup in the configuration file. The configuration file is located in the spooler hierarchy in the etc subdirectory and is named config.devid, where devid is an identifier derived from the name of the modem's device file; for example ttym2 for /dev/ttym2, term_10 for /dev/term/10. Consult hylafax-config(5) for detailed information on the contents of configuration files.
