Can't open serial port

[Rick N.]

I don't know what I've done.

When I try to open COM1 I get:

"Error -1073807202 occurred at Property Node in VISA Configure Serial Port (Instr).vi->Untitled 1

This error code is undefined. No one has provided a description for this code, or you might have wired a number that is not an error code to the error code input."

"VISA FInd Resources" reports 0 resources found.

any ideas?

Have you installed NI-VISA?

I thought I did.

How do I check?

It should show up in Measurement and Automation Explorer (MAX) click the Software folder to expand it, then click on NI-VISA. It should show the versions installed in the right panel.

Try to open the port using Windows Hyperterminal and see if you get an errror.
