Parallel port in windows NT

[paul_123456789@my-deja.com]

I am trying to use the parallel port with labview 4.1 in windows NT.
Windows NT security doesn't let me touch the parallel port, so my
application crashes every time that I run my VI.
Does any one knows how to access parallel ports in Win NT ?
Thank you very much,

Paul

You need to get this information from the KnowledgeBase at the NI web site.
There are several bits of information there that you will beed to access
the port.

Hello Paul,

Windows NT does not normally allow direct hardware access, as in
using LabVIEW's IN and OUT VIs.
The In and Out work under Win95. There is a third party tool call:
Peek/Poke 5.0 from Viewpoint. http://www.viewpointusa.com/peekpoke.html
I have use this software to control Pc hardware. The Peek/Poke software
gives you In and OUT VIs (that "get around NT security") that work under
NT.
I do not know if Peek/Poke works with LabVIEW 4.1, but I do know
that LabVIEW 5.1 does.

National Instruments has special versions of these VIs that are needed to access IO ports in WinNT. You can find them in the Developer Zone, the title of the document is 'Port and Memory Utilities for Windows'.
