Hi,

I have already finished such project using the GSM module of Ericsson (it
was GM-12). Now as it is not available any more I thought about new
possibility. Fortunately, my new GSM phone has a built-in modem. It is the
M35i which is virtually identical to C35i. It can be talked directly via
serial port with a prebuild cable.

Regards,
Imre
