Hi Spektro. It's been a long while, but as I recall since the 8 bit parallel port is open collector and bi directional, you just hook the two machines together without reversing any pin.You can still use the RS232 control pins for protocol as these are different pins on the overall 24 pin user port. The Code for RS 232 RX and TX are located at EA5B and EA95 in the Kernal.The parallel port is addressed as FD10.
