LPT Port Bit States

Hi, I'm trying to send High or Low signals to specific pins of the
LPT port using C++ programming... I don't have any clue where to start to find the memory addresses for the pins.... Help please.

Unless you're using DOS, you don't have direct access to the hardware anyway, so it becomes a pointless question.

Protected operating systems have a variety of ways of giving you controlled access to the hardware.

Which operating system do you have?

The program will be run in either dos or windows
