Maybe sometimes but not this time. You are looking for this:

ftp://ftp.heise.de/pub/ct/ctsi/directnt.zip

This is a generic IO device driver written for NT4. It also works with
NT5/W2k. I've used it only from C/C++ programs yet, but since it is a
driver it is used through Win32 API calls, for which the Ada bindings
exist. I'm not sure if it can be used in commercial software.
