Handphone to PIC

[DragonBall_6]

I was trying to use nokia 3310 to communicate with the PIC16F877. For example when I sending 1 via msg to PIC and PIC will activated the door alarm. When I send 0 to PIC and the door alarm will deactivated.
At the same time, when door alarm is corrupted (got ppl break into the house), I will be able to noticed it thru the handphone.

There are some kind of protocol that I have to consider about but I was beginner in this kind of project. I hoped that sombody will be able to provide me some guideline.

Thanks you very much......
