Problem: Your modem does not make a connection.
Solution: If your modem places telephone calls but never makes a connection, make sure you are dialing the right number.
The remote modem may be turned off.
Problem: You receive bursts of errors occasionally, but otherwise data quality is good.
Solution: The connection may have been established on
Someone may be picking up an extension con- nected to the line that your modem is using. If the modem is sharing a telephone line with other telephones, inform the other users when you will be making a data call.
Your telephone line may have a Call Waiting feature and a call is being received. See the previous Call Waiting discussion.
Problem: Random errors occur or data is missing in transmitted data.
Solution: Use the MNP or V.42 protocol if the remote mo- dem supports one of these protocols. See the table on page 23 for more information.
Select a lower baud rate in your communica- tions software and place the telephone 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 software are not using the appropriate flow control. Configure your communications software for RTS/CTS (hardware) flow control. Your computer now pauses for the transmission to be stored.
