I understand that it constantly looks at a pin and detects whether it is high or low, and when it detects a change, it records a new bit to a buffer, which eventually becomes a new byte in an 'incoming message stack' or something. I would have no way of figuring out how to reverse this process. Do you have any sample programs or resources that you know of? Thank you very much, Not at least I know it is very possible. -Marcus ---------- End of Message ---------- You can view the post on-line at: http://forums.parallax.com/forums/default.aspx?f=7&p=1&m=151101#m151113 Need assistance?
