Actually, the problem is more an issue of NT's overall operating
structure.  Win 95 apps can still touch I/O directly but not under NT -
that's why you don't see anybody releasing native NT versions of their
code.  This is especially problematic for emulator products, PC based
scopes, analyzers and other real time tools...

NT operates in protected mode.  When a process attempts to perform real
time I/O, layers of OS intercept the request, adding an indeterminate
amount of latency.  Permission levels tend be an issue as well.  Real
time OS resource is not directly accessible unless ring 0 drivers are
written to handle the I/O that is needed (especially comm ports and the
like), as well as the need for custiom ring 0 and 3 APIs to pass the
data back and forth.  What we're waiting on is the development effort
required of the tool vendors out there to adapt to a protected mode OS -
hence, Microchip, like just about everyone else, does not support NT as
of yet.
