
The i-modul Modem 144/56k 3.0 basic replies with
OK.

If the i-modul Modem 144/56k 3.0 basic does not respond, this may
have three probable reasons:
a) the i-modul Modem 144/56k 3.0 basic is switched off or
b) the i-modul Modem 144/56k 3.0 basic is not in configuration mode
or
c) the i-modul Modem 144/56k 3.0 basic is connected to another serial
port. Check it and repeat step 3.
4. Configure the i-modul Modem 144/56k 3.0 basic using AT commands.

A reference of the AT commands can be found in the chapter "AT
Command Reference".
5. Save your entries with AT&W.

Not all configurations at the i-modul Modem 144/56k 3.0 basic need to
be saved actively by entering AT&W. Some settings are automatically
saved immediately. We still recommend sending the command AT&W
to the i-modul Modem 144/56k 3.0 basic as your last configuration
step to ensure that all settings are stored safely and are available for
the next restart.
