Chapter 3 - Basic Modem Operation

Fewer programs are available to make use of the ZyXEL's fax features. A
commercial software which has found wide acceptance is FaxSTF. It is installed
like a printer driver, thus allowing you to send faxes from almost any program
which runs on your Macintosh. At the same time it allows automatic fax receiving.
This program includes a powerful line manager software which makes sure that
the fax software does not interfere with other programs using the serial ports. If
the modem is turned off when you start your Macintosh with the line manager
activated, the computer may seem to freeze for a few minutes. During this time the
line manager software tries to locate and to set up the modem. Turn on your
modem before you start your Macintosh to avoid this delay.
MaxFax is another fax software for Macintosh computers. On top of the fax
handling, it allows you to make use of the Omni’s voice features.
Drivers are available which allow use of the serial ports at speeds up to 230.4
Kbps. These drivers are currently available for Power Macs and AV Macs only.

If you wish to make use of the ZyXEL modem' special features such as voice,
special gettys such as mgetty or vgetty are needed. These programs are avaiable
from several ftp-sites. Some archives also contain source files.

) because some
applications may be confused by them.
