[FIXME: woefully incomplete. Is there a better FAQ on writing device drivers elsewhere ?]

Accessing ports directly under NT can only be done by device drivers which are installed and run with Administrator priviledges. Normally, you would write a specific device driver which uses the parallel port to communicate with the external hardware. The application program would then use this driver instead of accessing the hardware directly. While I have no doubt that this is what you will eventually do, this will take time to develope and test. A quicker solution is to use ready-made drivers which give programs direct access to the hardware. A device driver package such as DirectNT (containing giveio.sys and totalio.sys) can help here. The program is available free from Dr. Dobb's journal (see the article on http://www.ddj.com/ , Online library for May 1996, page http://www.digitalriver.com/dr/v2/ec_MAIN.Entry10?SP=10023&PN=1&V1=133372&xid=4909 , with the file itself accessible at http://www.ddj.com/ftp/1996/1996.05/directio.zip ). Another useful package directnt.exe, which can be found at http://www.ionet.net/~rbdavis/directnt.exe (from http://www.alternativecpu.com/ , page http://www.alternativecpu.com/subpages/files/files.shtml - the driver is used here to allow configuration of Cyrix processors under WinNT).
To use these device drivers, the application must simply open them as files (named "\\.\giveio") - the application will then have full access to hardware ports and can run the parallel port in the same way as under Windows 95 or Windows 3.1. An easier (but less secure) method is to use the totalio.sys device driver. When this is activated, *all* programs have total access to the hardware. I suspect that this will allow MPLab access to the parallel port under Windows NT with no modifications whatsoever. I have used this driver before to allow Windows 3.1 programs to access the parallel port.
Both these packages come with full source code, so you can see how they work. As far as I understand it, the packages are freely available and can be used in any way you like.

The "Windows NT Device Driver Installer" here has a single button that does all that.
