serial port not found in Labview

[redoo]

I dig out an old prototype in the lab which uses serial port to
communicate with the computer. The previous program was done in QBASIC
so I'm thinking of upgrading it to Labview. But then I noticed that I
can control the prototype in "Hyper Terminal", but not in Labview. I
then tested it with "Basic Serial Write and Read.vi" from Examples. The
same error message pops up. It reads like below:

Error -1073807202 occurred at Property Node in VISA Configure Serial
Port (Instr).vi->Basic Serial Write and Read.vi

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.

I know the serial port of this computer works cause I now am using
Hyper Terminal to manually control the prototype. I am using Labview
8.0 in windows XP.

I suspect that there is sth I missed. Any information would be highly
appreciated!

Do you have the VISA drivers installed? They are on the Device driver CD or you can download them from:

Exactly the same question was asked earlier today. The answer there is correct.

Problem solved after installation of VISA. This is a little
embarrassing. 😛

Thanks a lot, dan_u!

Priceless advice given (MasterCard), and LabVIEW doesn't take American Express either
