Carefull here, 'Real Time' is somewhat relative. To a person playing a
game a missed few milliseconds will never be noticed, to a stepper motor
missing a few milliseconds of steps will be big trouble.

Windows and its companion DOS are simply NOT real time systems. RT Linux
is only slightly closer to millisecond real time.
We are back to that discussion that dedicated hardware of some kind
(maybe with a microprocessor in the mix) is what is really needed for
good motor control.
