i need to read and write through the serial port, or any other port to an outside device, with no drivers. i just need to know what any pin mean, and how can i send it data(to each pin).

thank you. shmulik.

Techically, you're not really interfacing with the pins, you're interfacing with the controller.

Hi, thank you, but I find it no use. I dont understand whats this list all about, can u b more specific? thanks again. ;)

If you read the section in Art of Assembly, it pretty much explains RS-232 com ports (in chapter 22) and (parallel in chater 21).

And as for the file PORTS.txt file, it is just a list of somewhat standard ports on the IBM PC, for reference.
