Solving modem problems

Your modem is designed to provide reliable and trouble-free service. However,
should you experience any difficulty, the information in this section can help you
determine and resolve the source of the problem. If you cannot resolve the problem
after reading this section, contact your IBM PC HelpCenter for assistance.

If the problem is:
Modem does not respond
to commands
Modem dials but does not
connect
Here's what to do:
1. Make sure the modem is not configured with a
conflicting COM port and IRQ setting.
2. Make sure the communications software is configured
with the correct COM and IRQ settings (same COM
port and IRQ line as the modem). Your
communications software will not be able to send and
receive data if it does not have the correct COM and
IRQ settings of the modem.
3. Make sure the modem is properly initialized by the
communications software. The modem can be
improperly initialized if you have selected an incorrect
modem type. Select "Hayes Compatible" modem type
and "Rockwell" in your data communications software.
Select "Generic class 1" and "Rockwell" in your fax
and voice software, respectively. You may also be
prompted by the software to enter an initialization
string. Use AT&F as your initialization string.
1. Make sure the phone line is working properly. A noisy
line will prevent proper modem operation.
2. Check for busy signal, ringback, or a remote
answering system.
