If the Modem Dials Incorrectly
Check the telephone number you entered, including any
digits required for outside access or long distance.
In Control Panel, open Phone and Modem Options. Check the
dialing options—look for duplicate digits for outside access
or long distance.
Make sure the number you are calling is not busy.
If you are in a foreign country, the dial tone may not be
recognized by the modem. In Control Panel, open Phone
and Modem Options. Try disabling the option that waits for
a dial tone.
If you have call-waiting, disable it. Your telephone company
can provide instructions.
If the Modem Dials, But Does Not Connect
Make sure you are using an analog telephone line (2, 3, or
4 wires). You must not use a digital line. In a hotel, ask for
a data line.
Try another telephone line, preferably one normally used for
a fax machine or modem.
The modem at the other end may have a problem. Try dialing
to a different modem.
If the Modem Is Not Detected
Check the modem setup. In Control Panel, open Phone and
Modem Options. Check the COM port.
Open the hardware Device Manager. Select Start > Control
Panel > Performance and Maintenance > System. If the
modem is disabled, try to enable it. If it has a conflict, try
disabling another device.
If you are running fax software using fax Class 2, try using
Class 1.
