It will take you longer to send the 8 bits and parity than you receive the 8 bits, no parity. If this keeps up, you will get behind and need to buffer the receive characters.If you can get the sender to send 2 stop bits, this would solve the major problem with speed. But is the sender has a clock that is a little faster, then this small difference in speed would build up until you had a over run on the receiver. If you could get the sending unit to not send a continues data stream things should be better. As a visualization I have included a quick time video of Lucy and Ethel on the candy line. http://tinyurl.com/f94lv Bill ----- Original Message ----- From: "Regulus Berdin" To: "Microcontroller discussion list - Public."
