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, (with the comma), or by selecting it as a prefix, in
the software’s dialing directory.
Depending on your service, you might 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.
Problem
Random errors occur or data is missing in transmitted data.
Solution
Use the MNP or V.42 protocol if the remote modem supports
one of these protocols. See the table that begins on page 23 for
more information.
Select a lower baud rate in your communications software and
place the call again.
If both modems are using the MNP or V.42 protocol, the only
way this can occur is if your modem and communications soft-
ware are not using the appropriate flow control. Configure your
communications software for RTS/CTS (hardware) flow control.
Your computer will now pause for the transmission to be stored.
