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.
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.
