Although your suggestion is accurate, and I thank you for the effort, it's unfortunately not exactly what I need. It's OK though, I figured out the pin outs on the Laser128 (//c) and a DB-9 and was able to make a direct //c to PC null modem adapter. For those interested, here's the details: Format is PC pin # (Designation) - Apple //c Pin # (Designation) Pin 1 (DCD) - Pin 1 (DTR) Pin 2 (RD) - Pin 2 (TD) Pin 3 (TD) - Pin 4 (RD) Pin 4 (DTR) - Pin 5 (DCD) Pin 5 (SG) - Pin 3 (SG) Un-insulated braid cable on DB-9 solders directly to 5-Pin DIN metal housing. This is the shielding/GND cable. Pins 6-9 on the DB-9 are not used.
