I have a legacy app written in DOS Turbo Pascal that talks to hardware over a parallel printer port - i.e the printer port is used as 8-bit ports. Under Win98 it works fine in a DOS box but I need to run the same app in a DOS box on a WinXP machine. WinXP of course does not permit direct access to ports.
Does anyone know of a solution that works?. I've tried a couple that involve running an app to reset the permissions or such like but these hang my machine.
