Hi all, Timeout is a matter of transmission. Guessing how many time consumes the process of a " ; " is not. I think a ready/busy flag will help. HW flow control will help too if used to communicate the ready status. What do you think about?

It was ok as long as I used a "real" serial lne. With USB sticks I've encoutnterd very mixed results ranging from "works well" to "works not at all". The current echo-based flow control turned out to be very realiable for all connection types and the timeouts that occured had a real reason. Hardware flow control is of course better, but requires 2 hardware pins. Enoch mentioned that he wrote something, but did not published a recipe for it, IIRC.
