I did it once. There is a driver called rainport, which you can 
install. It redirects io accesses to a proper function which does the 
appropriate action. You can assign the allowed port adresses, so that 
it will only work with one lpt port and does not affect any other 
ports. The main disadvantage was that NT ran very very slowly, because 
of the polling of the parallel port. Every in or out command results 
in thousands of assembly instructions which you can clearly feel. So 
I´m not using it any longer. I´m using an old 486 with DOS (or Win 
3.11) to download and debug software or hardware.
