Set the baud rate in the terminal program to 57600 baud.
5.
Type in "
AT
" and confirm with "Enter".
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, check the
connection and if the device receives power at all. Continue with step
2.
The firmware upload can not function without the hardware
handshake. The input buffer at the serial interface of the i-modul
Modem 144/56k 3.0 basic overflows and the i-modul Modem 144/56k
3.0 basic resets itself. In this case, you will hear the relays click during
the uploads. It is possible that an error message is displayed.
Before you start with the upload, ensure that no other programs are
active on your system, which could interrupt the data flow at the serial
interface. Opening a DVD drive, playing music or connecting a USB
device can also disturb or interrupt the data flow. As a result, the i-
modul Modem 144/56k 3.0 basic may fail to function, and only INSYS
MICROELECTRONICS will be able to restore it.

Use the terminal program to send the file with the firmware loader,
such as "P9_02-16.S37".
If you do not send a firmware file, the i-modul Modem 144/56k 3.0
basic will terminate the procedure after approx. 60 seconds.
The upload progress is displayed by dots in the terminal window.
The i-modul Modem 144/56k 3.0 basic indicates the successful upload
of the firmware with e.g.:
Upload NV_Ram Data
If you didn't receive the previous message for a successful upload, the
upload has most probably failed. Try to reset the i-modul Modem
144/56k 3.0 basic and to repeat the process from step 4. If this fails
and the i-modul Modem 144/56k 3.0 basic does no longer react to AT
commands, please contact the INSYS MICROELECTRONICS support
department.
