The modem is not recognized by your computer
• Make sure that the line connected to the modem is
working and plugged into the appropriate port on your
computer. See your setup poster to make sure that the
connections have been made correctly.
• If the modem shares the telephone line with another
device, make sure that the telephone line is not in use
(for example, someone is on the telephone, or another
modem is in use).
• Use the modem cable that came with your computer.
Some telephone cables do not meet cable standards and
may cause problems with the connection.
• Shut down and restart your computer.
• Run Windows modem diagnostics.
To run modem diagnostics:
1 Close all open programs.

Modem Options. The Phone and Modem Options
dialog box opens.
4 Click the Modems tab, click your modem, then click
Properties. The Modem Properties dialog box
opens.
5 Click the Diagnostic tab, then click Query Modem.
If information about the modem appears, the
modem passed diagnostics. If no modem
information is available, a white screen appears with
no data, or if you get an error such as port already
open or the modem has failed to respond, the
modem did not pass diagnostics.
