PROBLEM DIAGNOSIS POSSIBLE SOLUTION
Your modem won’t connect
at 2400 bps with a 2400 bps
modem.
Your screen keeps
displaying random garbage
characters.
The modem you’re trying
to connect with could be
an older model that
doesn’t support error
control.
You could have a conflict
with the remote modem’s
settings for word length,
parity, and stop bits.
Your software and modem
might not be set to the
same flow control settings.
The best flow control
settings might not be
enabled on your modem.
You can disable error control on your modem by typing AT&M0
in terminal mode and pressing ENTER. Now try placing the call
to the remote modem again. When finished, reset your modem to
enable the error control features. In terminal mode, type ATZ
and press ENTER. Note: ATZ4 or AT&F1 are often the best reset
strings, as they restore hardware flow control defaults.
Set your modem’s word length, parity, and stop bits the same as
the remote modem or BBS you are calling. The most common
settings are: data bits=8. Stop bits=1, parity=none, flow
control=hardware (RTS/CTS)
Make sure the software and modem have the same flow control
settings (hardware [RTS/CTS] and software [xon/xoff]).
In terminal mode, type AT&F1 and press ENTER to load the
optimal settings.
