    For NT/2000, you need to use a Kernel-mode Driver, but Win9x permits direct hardware access, so different techniques are required for each platform.

    For more information, please review the info at www.lvr.com

    Do anyone know how to do hardware I/O in PBDLL that works in Win 98 as well as in NT4?

    The "faq" link on the Forum pages goes to the FAQ for the forum software. However, we also have a Frequently Asked Questions forum, which is something completely different.

    John,

    I for one would be interested in learning more about
    PP I/O from your routines.

    Cheers,

    Michael

    I use the parralel and serial ports for testing digital control modules.
    I have the routines for reading ,writing from / to the data, control and
    status registers of the paralel port + general prpose I/O.
    These routines as they stand allow for ~ 10mSec best response
    in multi threaded program.
    If you want more info let me know.

    I've posted the p port info under WIN 9x parallel port how to.
    There is a description of the port registers and the .INC file I use.

    Take a look at www.lvr.com for parallel port programming info and libraries, etc.

    Thanks Tom,

    I checked the FAQ ,seems to be about using the forum?

    Thought you might have meant the archives, so I did some searches and found bits and pieces (mostly serial port)

    The main goal of the post is to find like-minded programmers as the bulk of the programming done (based on posts) is Database/ Internet / Business applications.

    I am currently writing machine control code in DOS w/PB35. One look at the windows vs. dos post numbers shows where we are headed. I have been told all the can'ts of real-time in WIN and am looking for someone who knows some "cans".

    I believe this is covered in the FAQ section. You might also check the Add-on Vendors pages.

    Real time P Port control / vxd

    Hi all.

    Anybody doing real time parallel port control under Win9x? How?
    What level of "real-time" is attainable?
    If needed,where to find VXD for same?

    Thank you in advance.
