Problem:
Your modem disconnects while
communicating with a remote system.
Solution:
The remote system has hung up.
The telephone line disrupted your call. If your
telephone service includes Call Waiting, turn it
off if possible before making modem calls. Ask
your telephone company if you can temporarily
disable Call Waiting by pressing *70, or another
code. If so, include *70, (the comma is part of
the code) or the other code as a prefix with the
telephone numbers in the software’s dialing
directory. Or you can add *70, or the correct
code to the dial string (be sure to include the
comma). Note that this helps with outgoing but
not incoming calls.
Problem:
Your modem does not make a connection.
Solution:
If your modem places 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
poor-quality or noisy telephone lines. Hang up
and place the call again to try to obtain a better
connection.
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 Call
Waiting discussion above.
