Problem
Your modem disconnects while communicating with a remote
system.
Solution
The remote system has hung up, and you need to reconnect.
The other most common sources of interruptions are Call Wait-
ing or someone picking up an extension phone.
If you have Call Waiting, you can usually temporarily disable it by
including
*70,
(including the comma), or by selecting it as a pre-
fix, in the software’s dialing directory.
Depending on your service, you may not be able to disable Call
Waiting for incoming calls. If your incoming data calls are fre-
quently disrupted by Call Waiting, you should consider dropping
the service or installing a separate phone line without Call Wait-
ing.
Problem
Your modem does not make a connection.
Solution
If your modem places calls but never connects, make sure you
are dialing the right number and that the remote modem is turned
on.
