I haven't programmed for Windows since Win95 or for parallel ports under Windows. However, I did write some C that had to access a serial port. That was a bitch because neither DOS7 nor Win95 provided a shred of support for serial hardware - you either rolled your own from scratch or bought a 3rd party library. I suspect the same applied to the parallel port too and that Windows doesn't supply direct assess because it expects you to use the print spooler. However, I don't know if this situation improved with Windows 2000 and later versions. Any other ideas? > > There's no way you can run Windows drivers under Linux, so I think your best move is to contact the programmer's source company and see what they suggest. Of course, if your Linux box has enough grunt, you might consider running the programmer under Windows inside a VM. Sorry I haven't any better advice. Martin
