PC Parallel port trouble

[Bub]

Hi all,

I've got some problems with my parallel port... I use it to control relays
but when I write "0" (Labview application) it doesn't stay and change to
"1" in less than 1s !!!! (Win98 SE)

When I do the same thing in dos mode it works normaly

Thanks for your help

Check that the port settings in your bios are set for standard
parallel port and not enhanced etc, I have seen various dongles get
tripped up with the same trouble and have had various issues with this
on several motherboard/windows combinations in the past myself.
