Why, YES. You certainly can. It would be hard as I have looked at it, in detail. The biggest technical challenge is decoding the Bell202 AFSK tones (1200Hz and 2200Hz). At 1200 baud, you get only one cycle of the 1200Hz tone. Zero crossings are probably NOT good enough with a noisy (less than full quieting) signal).

There are at least two AVR packet projects around.

If you want to discuss this in detail, you are welcome to PM me on this board (click my name or click the PM button at the bottom of this message).
