Parallel port problem

Tech Tip: Click here to run a free scan for Windows Errors and optimize PC performance



Always nice to start with some alliteration

I have a parallel port dongle for some old 16 bit SCADA software
(intellution fix v5.6) and this works fine on a Dell latitude laptop running
XP pro.

When I came to try it on desktop PC's the SCADA startup screen freezes when
trying to access the dongle.

One of the desktops is running the same version of XP Pro and uses the same
parallel port (and ParVDM.sys) file. The other a running either xp pro sp1,
xp pro sp2 or xp home sp2.

If I disable the parallel port in Device Manager the startup screen is fine
and reports that the dongle is missing (and allows demo mode to run)

I've tried altering BIOS settings and driver settings (use interrupt etc)
but to no avail

I also tried using user port drivers (PortTalk, UserPort) but I suspect part
of the problem with them may be that the startup screen then loads DLL's or
other exe's

I've contacted Intellution (the SCADA programmers) and they just said sorry
our stuff doesn't run on XP unless you give us £10,000 for our nice new one.

Any ideas anyone?
