General Troubleshooting

Problem: The software cannot find the modem and the
modem does not respond to AT commands.
(The following solution applies to many
other problems as well.)
Solution
The most common problem with modems is
:
that the communications software is not con-
figured for the same COM port as the modem or
that the USB faxmodem is not selected under
the software.
If you have a PC, check which COM port the
modem is using and make sure that the soft-
ware's COM port setting matches the modem's
COM port setting. From the Windows Toolbar,
under Settings/Control
Panel/Modems/Diagnostics, click on the COM
Port for your modem, then click on More info.
If Windows displays the modem's ATI re-
sponses, the modem is working.
If you have a Mac, make sure that the USB
faxmodem is selected under Settings in the
application software.
Problem The modem speaker volume is too low or too
:
high.
