To anyone who may help:
We are a group of engineering students and part of our final project consists of interfacing a microcontroller to a phone (i.e. through a serial port) so that we may have the phone send SMS if the microcontroller software chooses to do so.
What we are not sure of is how to make this connection between the microcontroller and a cell phone. Is this a serial connection? what communication protocol does it use?
Your help on this would benefit our project tremendously. Thank you in advance for your help. Please cc any answers to email@example.com
