I doubt that accessing those memory locations will get you anywhere under Win32. Gotta go through the API.
I don't know about parallel & game ports, but serial ports are exposed as files.

Maybe you can get hold of a parallel port in the same way.

Well everything looked to go fine but...
I guess i have to grab my old vC++ 1.0 special edition and make a dos program but then are the _inp and _outp yet usefully. As i quickly looked i can´t make program that uses segmentary memorymodel(Brings back to min "Tricks of the gameprogramming gurus"). This is getting enough hassle printer functions could work but if won´t what a work and I can´t code MFC because I´m turning to Linux and thinked meicrosoft go heck with your Api but my school has only microsoft based computers.
As I looked help along seems that printer functions theoritically could work but has someone knowledge about some nasty windows feature like what´s the format of data send and received at the printer or is it only in plain binary format in pin order what was in Stevens post. I´m not going to do it with serial port it´s too complicated me i´m just soon 15 years and not super experied with electronic works. Well if I use printer functions i definately had to add flagg is data get.
Aah this get comlicated my work is never ready
Some microsoft guy should help me.Is here some windows guy
