I've got a problem that i Can't solve yet.. I'm Using the VISA resource name to communicate with my GPIB Devices on the GPIB bus. I've made a program that reads a couple of value's from 2 HP34401 multimeters. On this computer it works fine, but when I use the program om a Dell Optiplex GX110 my VISA resource box crashed.
I can hover with my mouse over it for a couple of time's but after 3 or 4 time's it just crashes. My resourcebox is filled with 2 HP34401 and the COM1 and LPT port. But on the other computer the LPT and the comport are assignt with:
ASRL1:INSTR
ASRL2:INSTR
I've used the NI-MAX program that can scan for GPIB devices and also there I can see the strange definition of the COM and LPT port. My problem looks a bit like this:

I have a normal National Instruments GPIB PCI controller in my computer and the same card is used within the GX110. The weird part of it that I Can communicate via NI-MAX (Just sending query commando's). The problem has to be the VISA session.
Can someone give me a hint or a solution ?
Thanx!
