GSM modem

This is a very __stupid__ trial, using a serial modem to make it work with Android. [LOL]

GSM modem:

you can use any serial GSM modem. standard modem supports AT standard command. i test with PC first, and it worked fine. both sms function and phone function. first time i use the same cable with development board and it was not working at all. then i modified the cable, if you face the same problem, make sure the serial cable is correct as Plug/Plug Crossover :


changed on one side 2 with 3 and 7 with 8.


check the baudrate with stty -F /dev/ttymxc2, connect to a PC, start a terminal prog with the correct baudrate.
then you can make echo AT > /dev/ttymxc2 and you should see it on your pc.
You can also do a getty -L 115200 /dev/ttymxc2 to open a console.

You can change the baudrate with stty -F /dev/ttymxc2 {baudrate}.
