I want to know how i can enable parallel port using C++ .
I mean what is the code i need to help me in programming ?

 

I didn't know they had to be enabled. Aren't they available all the time?

 

Here is a link to everything about parallel ports - http://www.beyondlogic.org/spp/parallel.htm

You are aware that this port is not found on modern computers?

 

I didn't know they had to be enabled. Aren't they available all the time?

having done some VB6 code to do bit banging on a parallel port (unfortunately - i knew little else at the time- VB is annoying at times) i recall having to select and enable a port before use, i believe this grants access (through windows layers at least) to a program to transmit and receive signals on the port.

might be wrong though, but i do remember there being a find port and select port function in this book:

which was very helpful
