The mgetty package contains a "smart" getty which allows logins over a
serial line (i.e., through a modem).  If you're using a Class 2 or 2.0
modem, mgetty can receive faxes.  If you also need to send faxes, you'll
need to install the sendfax program.

If you'll be dialing in to your system using a modem, you should install
the mgetty package.  If you'd like to send faxes using mgetty and your
modem, you'll need to install the mgetty-sendfax program.  If you need a
viewer for faxes, you'll also need to install the mgetty-viewfax package.
