Sounds like Windows 98 is keeping control over that hardware resource and not letting your program touch it. Does your program run OK under Windows 95? Note also that the virtualizing makes IO commands run much much slower. Does timing matter to your program? ^ permalink raw reply [flat|nested] 3+ messages in thread

It would make a nicer app. as well. If it's a Win98 port control problem, rewriting in an MS V language would make no difference - except to lose the ability to run under DOS. ^ permalink raw reply [flat|nested] 3+ messages in thread
