There is no dial tone
1. Ensure that the telephone cable is securely connected at both ends.
2. Unplug the telephone line cable from the computer, and connect it directly to a telephone from
the wall outlet. Check for a dial tone. If there is none, the problem is in the telephone line or
system. Call the service provider.
•
The modem cannot complete a connection to another modem
1. Ensure that your modem is dialing the correct number. Ensure that you've specified the correct
area code, if one is required.
2. Determine whether the remote modem is correctly configured to communicate with yours.
•
The modem does not answer incoming calls
1. Ensure that the automatic answer parameter is set to one of the enabled options, using the
ATS0 command (ATS0=1 to answer after one ring, and so on).
2. Ensure that no other devices, such as fax or answering machines, are answering calls before the
modem does.
•
The modem disconnects while transmission is in progress
1. Ensure that the telephone cable is securely connected at both ends.
2. Ensure that call-waiting is disabled. In most areas, the command *70 or #70 disables call-
waiting. Check with your telephone company for the correct key sequence. (With call-waiting,
the incoming call's click sound may be disrupting your call.)
•
Data is not transmitted or received for unusually long periods of time
Re-dial the call. (The telephone line connection may be poor.)
