I have WinXP Prof and I have an attachment that plugs into the LPT1
Port (a Dongle) that works the software for this equipment but it comes
up error all the time with the Dongle plugged in or not. I was told to
get UserPort and I did but I do not know how to set it up and I don't
think the supplier does either so I am completely stumped and would be
grateful for any information I can get as until now I have had none.
