Hi Ryan,
I found the example at:-
http://www.bernardotti.it/portal/showthread.php?t=17537
to be very helpfull.
I modified it (below) to detect a phone in "RING". My GM862 then does a "hang up" (hence no phone cost). The GM862 then reads the GPS and sends an SMS to a fixed phone number (sub. in yours at the correct position in the code).
I use SER.send commands to debug and watch what is going on in the roundsolutions "rsterm" hyperterminal.
I compile the script in rsterm to get the .pyo which I then upload, enable and run. It works great.
Gotta give credit to Flavio Bernardotti (what a name..sounds good enough to eat!); without his example I would have got nowhere.
