I think hylafax will let you do that. Here's something from the hylafax
man page:
HylaFAX is a telecommunication system for UNIXtm systems.
Among the features of HylaFAX are:
HylaFAX runs as a network service; this means a modem
may be effectively shared by a large number of users.
HylaFAX can be configured to work with a wide variety
of modems on a wide variety of systems.
Access to the system can be restricted by the adminis
trator to selected hosts and/or users.
Transmission requests may be processed immediately
(default) or queued for processing at a later time, in
the manner of the at(1) command.
Remote facsimile machines may be polled to retrieve
publicly available documents.
POSTSCRIPTtm and TIFF Class F documents are passed
directly to the fax server for transmission; the system
attempts to convert other file formats to either
POSTSCRIPT or TIFF through the use of an extensible
file typing and conversion facility. In normal opera
tion ASCII-text, troff(1) output, and Silicon Graphics
images are automatically converted. Additional file
formats can be added; see typerules(5F).
Could be worth looking into, but I have to admit that I have not worked
with it directly yet myself. SuSE Linux has a java-based front end to it
called susefax that I tried to set up, but haven't gotten going yet.
(Faxes are not a priority here.)
