Yes. A "plain old modem" can't do group 2 or 3 FAX operations. A
FAX modem will act as a normal modem AND can act as your FAX machine.
If it receives a call, it checks the carrier tone. If it appears to
be a FAX, it'll trigger your FAX software and receive the FAX. If it's
a regular data call, it'll launch the login sequence on your machine.
Since I have a scanner, printer and a FAX modem, I combine them via
Linux into an "all-in-one" thing like HP sells. Incoming FAXes come in
and are spooled up on the machine for me to look at. If I want the FAX,
I print it out. I don't waste paper on junk FAXes (and I get a ton of
those).
If I want to send a FAX (not that common, but on occasion I do), I scan
it in and use efix to convert the file to FAX format. I then use efax
to send it out via the modem. Yes, sending faxes is a bit harder than
using an all-in-one or FAX machine, but just barely.
If I dial into my machine (almost NEVER since I'm on cable modem), I can
do that as well.
I prefer using the separate boxes for several reasons:
1. I already had them (and I'm cheap!)
2. Often the "all-in-one" scanners aren't as good (lower
resolution) as a real scanner.
2. The "all-in-one" boxes often require special drivers that
the makers simply won't provide to us open-source guys, so you
have to roll your own or wait for linux-printing.org to come up
with one.
Do what you wish. See "man mgetty" for details about the incoming call
handling if you wish to follow in my well-trodden footsteps.
