Dialup Modem Settings
Configuring Non-OEM Modems with Software
The apC/8X automatically sets up modems that are configured using software
commands, based on the modem’s default settings. However, the default
settings of some modems do not turn command echo off and enable DTR.
This causes unpredictable behavior when the apC/8X is used in dialup mode.
To ensure proper operation with modems normally configured with software
commands, you must program the modems manually at a terminal with the
following Hayes Modem programming commands.

Note:
If your modem does not accept the Hayes Modem commands,
consult the modem documentation for the equivalent commands.
Perform this procedure only once after installation, since the user-defined
configuration will be restored with each power-up. Consult your modem
documentation for more information about configuring your particular
modem.
