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.
