I want some help regarding PCI Parallel Port interfacing in C++.
Can anyone help here?
If there is a built-in parallel port, the address to access it is 0x378 or 0x278.
Now, I have two problems here:
1 - Its PCI Parallel Port (address is D070 as Device manager - resources say)
2 - I have Windows 7 64bit.

I would appreciate if someone can assist here.
Tried porttalk and some other softwares, but they ain't working on 64 bit windows.

Hahahaha! Windows 7?

Win98 was capable of real-time directly accessing the parallel ports by their address, but after that you get into deep water.

You need to find an API library component for your C++ compiler that allows SOME level of parallel port access, but even if you succeed it will be slow and clunky as it will be completely subservient to Windows and everything it wants to do. So don't even try some fast real time parallel port driving or reading.

Sorry to be the bearer of bad news but the parallel port was considered obsolete in the mid 90's.
