(...) You have to re-write the bit_delay loop to take up four times as much time. Just multiply the delay count value by four, e.g., "LDAB #148". Fred (following is the 9600 code.) * take up 0.1042 millisecs * 208 cycles bit_delay LDAB #37 bit_loop (...) (27 years ago, 16-Feb-98, to lugnet.robotics.handyboard)
