Re: Winwods NT

Windows NT does not allow direct access to the hardware from user
mode code. You can use the general Port I/O driver from the DDK for
this or write your own application specific driver.

If you want to run your code to behave properly, NT does support real
time priorities that run at higher priority that other windows tasks.
A properly designed system needs to take advantage of this and create
tasks that run at real time priorities for time critical processing.
