Can somebody suggest a low level parallel port driver for the PC
(windows 2000)?

This is to interface some digital controllers using TTL logic. The
..sys driver should preferable be free, easy to use, and allow very
fast access to the I/O ports. High level software would be written in
C

I have been searching the net, but there seem to be too many offerings
and not sure how good they are..:)-(

I thought this newsgroup would be a good place to ask as there should
be somebody here that's gone through this process before!!


Thanks in advance

The one practically everyone uses is actually an example from "Writing
Device Drivers" book and is distributed for free by
http://www.driverlinx.com/DownLoad/dnload.htm with source as well as
compiled version. There's example code in C and VB. Since the driver merely
sets the permission for the user space to issue the io instructions, it's
about as fast as possible.

The driver shows up as "DriverLINX Port I/O Driver" under windows device
manager.

I use a free progrm called userport (search google for
userport.zip) to get userlevel access to my parallel port pins.
I've got a page below that shows how to use the parallel port to
control a simple webcam switcher just using batch files.

Excellent program, with allowio.exe that's included with it you can
open any port to any program. Works great to make older LPT port
programs run with Win2000/xp.

Also look at the menus at the blue bar in the page, there is a lot
of good info here.
