SYMPTOM POSSIBLE REMEDY
• Verify that the communication software
is set to the same communications port
where your modem is attached (e.g.,
COM1, COM2). Check IRQ settings in
your software and on the modem.
• Try typing AT&F to reset the modem to
its factory defaults.
• Move the modem to another serial port
(power down the host computer first). If
the modem works after being moved,
it’s likely the problem is not with the
modem.
• Make sure the echo command is set to
ON. Change to echo with the ATE
command.
• Make sure the local (yours) and remote
modem configurations are compatible.
• Verify that both modems are operating
with the same settings, speed, data,
parity, and stop bits.
• The software may not be set for correct
terminal emulation. Configure software
to correct type. ANSI terminal emulation
is most commonly used.
• Power down your system and re-run
your communications software. Check
software settings.
• Exit the communications program and
restart it.
