Hi to all!

I am creating a special made data adquisition software for one of the
Physics labs of the university in which I work, and I have a mixed DOS/Win95
and Linux network. My idea is to create a software that has to have the same
look and feel under DOS and under Linux (probably using ncurses or sth. like
that).
So I decided to use DJGPP for the DOS/Win95 machines and the GCC of my
RedHat 5.2 in the others. As far as I know, under DOS there are a couple of
functions (inportb() and outportb() ) which handle the access to the
hardware ports (I need to access port 0x220), but I do not know if they work
under Linux... I've tested, and they do not seem ot exist under Linux, so
either I have to use some other function or I need to add another include
file under my Linux  project.
Does anyone knows if there is a protable way to access hardware ports
(without assembler)? Are there any standard functions to do this?

Thanks in advance!
