There are no Diagnostic Control Panel (DCP) functions
unique to fax operation. If your fax software requires that
you change the configuration of your modem, see the
appropriate sections of Chapter 9, Configure Branch.
The DCP is disabled during fax operation.
Your fax software uses AT commands to tell the
modem what to do. These commands, and the replies your
modem makes (such as “OK”) may be displayed on your
computer terminal during fax operation, but this depends
on your software. You do not have to issue AT commands
yourself, unless you use AT commands to configure the
modem.
For more information about fax operation, see the
manual that came with your fax software.
