um... sorry Ken, you are absolutely right.
my WinXP does not allow writes to the IO port. It does on 98, and i mistakenly
thought it was working on XP as well.
technically, I only need this to work on the manufacturing's Win98 machines,
and now methinks the working C-code might be just fine af

it won't return a value, but it still has to go back to the caller.

Hey all
we have some devices at work that are controlled by sending signals via the
computer's parallel port. (because all the serial ports are being used
elsewhere)
the parallel port (LPT) has the address 0x378. to do this in C, its quite
simple:
void parallel_device (int state)
{
