Hello Kickin,

Kickin>>The only problem I see is the data itself. You mentioned using a low baud rate (outputting the data as text?). Would this be better than devising a 'morse code' style system, sending different length pulses - perhaps a short one to mean '1', and a long one to be a 'break'??<<

This is all up to you...How you send your text is up to you...I prefer Morse... But hey...when you read 40 WPM in your head, its easy to decode <g>. IT also needs no special equipement like a PLL for different tones (like in RTTY). Dashs are 3 times the length of dots... space between words is equivalent to a dash. space between dots is a dot.

I have no experience with Cell Phone and PIC connectivity. But, if you want to use SMS, maybe someone like Ralph can help you... I believe he has much experience in Cell phone/PIC communication. I do not know how much data you are sending, but 40 WPM is approx 200 characters per min...(A word is considered to be 5 characters in length).

I doubt if I have helped you much, but maybe this will give you some ideas.
