I don't know the specifics, but NT and 2000 at least (Win98, too,
probably) do not normally
let programs have control of the physical parallel port. They are
supposed to access it
through a printer driver, which is fine if you are using the port for a
printer. If you are
using the port for a license key ("dongle"), PROM programmer or other
device, you
generally are supposed to provide a vxd (virtual device driver) for that
purpose.
Some systems allow DOS style access to the device after some security
features
have been turned off, or priveledges given to the user or program that
needs the
special access. Other systems don't allow it, period.
