    Question Writing to parallel port in Win NT

    I am using VC++ versions 5 and 6. I want to write to the parallel port of a PC.
    Although I can achieve this successfully in Win 95 and Win 98 using the function _outp(), I get an application error in Win NT.
    Any ideas what I can do to solve this?
    Many thanks

    Look up CreateFile()...this should be aple to latch onto "LPT1" or whatever...
