Your fax communications program only sends and receives
faxes at 14,400 bps when you have a 56K modem
• Current fax technology only supports a maximum send
and receive rate of 14,400 bps.
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. To make sure that the connections have been
made correctly, see your setup poster or “Connecting
a dial-up modem” on page 17.
• 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 required cable
standards and may cause problems with the modem
connection.
• Shut down and restart your computer.
• Run Windows modem diagnostics.
To run modem diagnostics in Windows Vista:
1 Close all open programs.
2 Click (Start), then click Control Panel. The
Control Panel window opens.
3 Click Hardware and Sound, then click Phone and
Modem Options. The Phone and Modem Options
dialog box opens.
4 If the Location Information dialog box opens, enter
your location information, then click OK.
5 Click the Modems tab, click your modem, then click
Properties. The Modem Properties dialog box
opens.
6 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.
