Im a complete beginner with Arduino so i hope you'll be able to help me. I tried searching but i didnt find anything (or didnt think its the same thing).
Right now i have a computer interacting with an Arduino (Diecimila) over the USB port which works fine. I would also like to connect a mobile phone to send text messages via Arduino. But now I have no idea how to interact with it. If I do Serial.println(...) and Serial.read() I will communicate with the computer. Is there any way to open another Serial channel? I would also welcome any other ideas you might have. Im guessing connecting the mobile to a computer is also a possibility.
