This section describes some of the common problems

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.

1.

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.

2.

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
press ENTER. The factory default allows the modem to
display responses after a command has been executed.

3.

Make sure the baud rate setting in your software is set to
57600, 38400, 19200, 14400, 9600, 2400, 1200, or 300 bps.
An incorrect baud rate prevents the modem from operating
properly.

4.

Make sure that the modem is not conflicting with another
COM port or IRQ in a non-PnP system.
