Hi everybody, In one of my applications, I need a serial RX/TX routine capable to 'recognize' the speed of the serial line, so it can adjust itself to that speed (eg. I have a '84 based 'host' to which I want to attach few 'terminals' working at 1200, 2400, 4800, 9600 baud). Did anybody try something similar? Any ideas on how to determine the RX speed, possibly without loosing a byte of data? Thanx, Max
