As I mentioned before, I'm just doing such a thing for a customer in
these days. I hope I will have a little time in august, so... just in
case, Mark, would you tell me to which ports would you need access, at
least at the beginning? Then , if the things works, we could make a more
configurable and wider device driver.
In my idea, a first/beta version would include read and write access to
a couple of ports (that you must define BEFORE, as you install the
driver in NT), and read/write could be performed using Win32 function
DeviceIOControl. BTW, it works in both Win95 and Win98, so this solution
would be good for all platforms.
