Use of Parallel Extender under Windows 2000 or NT4

Keywords: 	   parallel extender NT

Question:

I need help, becource i have found a way to use parallel i/o adresses under w2k or nt 4.0. it works fine with mapmemplus, it brakes the hall, and it is easy to use the portadresses of nt. but now i have the problem, the WWPAR34i.DLL dosnīt work on W2K or NT. Is there a way, to brake the dll, so it work fine?

Answer:

Sorry, our parallel extender does not work with Windows NT or 2000.

I'm not sure what you mean by "braking" the DLL so that it will work under Win2K.

The basic problem is that WinNT and Win2K protect the physical hardware from being accessed by a user-mode program. You have to be a device driver to directly access the I/O port addresses of the LPT port(s) on your system.

I do know of a little utility device driver called "TinyPort" that runs under NT/2K which is used to give C programs access to the I/O port addresses used by the LPT port(s). Perhaps the TinyPort utility in combination with the parallel port extender would work for accessing the LPT port(s) under NT/2K.
