Section Six - Troubleshooting
This section describes some of the common prob-
lems you may encounter while using your modem. If you
can not resolve your difficulty after reading this chapter,
contact your dealer or vendor for assistance.

Modem does not respond to commands.

1. Make sure the modem is not configured with a
conflicting COM port and IRQ setting (see Sections
2.2-2.5). As an example, your modem can not be
configured as COM1 if another device in your system
is also configured as COM1.
2. Make sure the communication software is configured
to “talk” to the modem on the correct COM port and IRQ
setting (same COM port and IRQ setting as the
modem). Your communication software must know
which address your modem is using in the system in
order to pass data to it. Similarly, IRQ settings must be
set correctly to receive data from the modem.
3. Make sure that your modem is initialized correctly.
Your modem may have been initialized to not display
responses. You may factory-reset the modem by
issuing AT&F and pressing ENTER. The factory
default allows the modem to display responses after
a command has been executed.
4. Make sure the baud rate setting in your software is
set to 115200, 57600, 38400, 19200, 14400, 9600,
2400, 1200, or 300 bps. An incorrect baud rate
prevents the modem from operating properly.
