H2200, Familiar, Enfora GSM0110

I have a iPaq H2200, running GPE and Familiar from an SD card, with an
Enfora GSM0110 GPRS modem card in the CF slot. I am trying to set up
the GSM0110 and so far have not been able to access it.

The low level documentation of the GSM0110 is not great. However, it is
clear from the documentation that, in a PocketPC, it is configured as a
serial modem. Also, the data sheet says that it uses an AT command set.

I have tried to get a response from the modem using minicom, with the
serial port set in turn to /dev/ttyS0, /dev/ttyS2, /dev/ttyS3,
/dev/ttyS4. I type +++<Enter>, then AT<Enter>. No response.

Any suggestions as to how I can check if the modem is present, and if
not, how to access it?
