Hi,

I have the source code of a small application that reads and writes the
parallel port.
The application works fine in Win95/98, but I find that when I try to
execute it in
win2000/XP it doesn't work.

I've found in internet a utility that installing previously a special
driver, I get what
I want, but using an uncomfortable command line.

Due to I've the source code I would like that my application didn't need
installing this driver nor using this command line. I would like include in
my application the code needed to read and write the parallel port in a
transparent way.

It doesn't matter if such code is x86 assembler.

Anybody has had such problem?

Thanks in advance.
Jose Manuel Lopez.

Try asking on a programing group. Unlike DOS or Windows 9x, Windows
NT/2000/XP does not allow direct access to hardware so the code will
have to be rewritten or you will have to use a workaround like the one
you found.

I load a driver called userport that provides DOS based programs access to
the parallel port.
