You are having trouble making a Reliable connection.
Problem:
Solution: One of the following may be the solution:
Your modem is not set to make a Reliable connection. Issue AT&F or issue AT\N7.
Communication Standards and Result Codes provide more information.
or
The remote modem does not support MNP or V.42. A Reliable connection is not possible in this case.
or
The remote modem supports MNP or V.42, but it is not in Reliable mode. Have the remote modem
operator change to Reliable mode.
or
The remote modem supports MNP or V.42 and either gets confused by the length of time your
modem takes to "negotiate" the connection or confuses negotiation characters with the remote
computer's log-in sequence. In this case, issue AT\N (Normal) to disable error correction and data
compression, and then dial again.
or
The telephone line quality is so poor and noisy that it interferes with the negotiation process. A
variety of factors can cause line noise. You can try to make a Normal connection.
Problem:
Your modem is not recognizing busy signals, or your modem is interpreting other signals from the
remote location as busy signals
Solution:
Be sure the country code is set properly. (Feature #120, if your modem supports it). Be sure your
modem is set to recognize dial tone and busy signal by adding an X2 to the end of your
initialization string. Contact Technical Support for assistance.
Problem:
You have connected to a remote modem but your computer has frozen up or all you see on your
screen are garbage characters.
Solution:
You have made a Direct connection, but your computer and modem are using different rates. Use
your software to change the computer rate so it matches the connection rate given in the CONNECT
result code.
or
Your computer and the remote modem are set to different data bits (word length), parity, and
number of stop bits. The most common are 8 data bits (8-bit word length), no parity, and 1 stop bit
(8, none, 1). Change these settings in your software.
or
Your computer and the remote modem are set to different terminal types. Change these settings in
your software.
