Serial port doesn't appear as a VISA resource when running LabVIEW in a VM.

[jmburns]

I have LabVIEW 8.6 installed on a Virtual Machine running Windows XP.  I have access to the Serial Ports of the PC through a terminal emulation program, and can see them under Windows Device Manager.  However, when I place a VISA Resource Control on the front panel of a VI, it doesn't see anything.  How can I access my Serial Ports?

Thanks,

Jason

What does VISA Find Ressource say?

If you really can't find any interface, so you can write the port number e.g. "COM3" into a string control and connect them to VISA Open.

Did you install NI-VISA on the virtual machine, or just plain LabVIEW? If the latter then the VISA control won't show anything.

Oops.  I'd been given the VM by someone else and thought everything had been installed, but apparently not.  I installed VISA for real, and now it's working perfectly.  Thanks for your help!
