Hi Jacob
Thanks for answering my post. I am pretty sure you are right. I knew that DOS pretty much only has a root user and that user can access parallel ports and such and I knew that regular Posix users could not access hardware like this but I thought it could be by-passed with root access.
However, if that was the case, people could still set pointers to hardware addresses in C and skip the use of outb(and similar calls).
I can bind to ioperm and outb but at this point C is just pestering me. I want to use C when I choose to use it but it just seems to be everywhere and it won't leave me alone.
I just want a break from C, it's more about fun then it is about getting stuff done.
If I find a solution, I will post back to leave a trail of breadcrumbs for others.
Thanks again-Patrick
