Troubleshooting

Most modem problems are a result of incorrect cabling or
incorrect settings within your communications or fax software.
This chapter provides a list of common problems (P:) that you
may encounter after installation, followed by likely solutions (S:).

Configuration Problems

P: Your modem stops responding after it receives a
command string from you or your communications
program.
S: Reset the modem's default configuration with the AT&F
command.
P: You do not know what initialization string is required
for an application.
S: If the default configuration does not work satisfactorily,
follow the guidelines in Appendix C.

Power Problems

P: Your modem does not power ON, or does not respond.
S: Ensure that all related software is directed to the correct
COM/IRQ combination. Check your COM port using the
Control Panel Ports icon under Microsoft Windows, or the
"Test an installed modem" feature of the COMTEST
program. Set QuickLink II Fax to communicate with this port
using the Modem Setup window.
