How do I send something to the 8 data bits of the LPT if I'm using Windows 95.
Watch Question

It all depends on what OS you are using!


I think that your are using windows 95 or NT therefore the answer could be:
-In the same way that you do it under DOS by using the outp/inp function


Edited text of question

Maybe you should have a look at the Win32 help file.  You can open communication resources using CreateFile and you can write to LPT this way. (CreateFile("LPT1:", ... or something))
You can access ports directly after getting there handle using CreateFile(). Then you can send data to this port just as to a regular file
