If you can get down so low in baud rate, then you can fudge it in software. Set the port to the single stop bit, and make a transmit character function that outputs a single character and a flush(), and then waits for a bit time or so - time.sleep(0.022) will do the trick - means you have to make a string transmitter that calls your character transmitter - you cannot just write a string to the port - but that is no great hardship. The receive side will not be a problem, as the syncing is done every char. - Hendrik -- http://mail.python.org/mailman/listinfo/python-list
