Serial VI's Functioning using On Windows VISTA

[PSPS]

Hi Everybody,

Serial VI's of Labview 6.1 using on Windows XP are fine but using them on Operating System Windows VISTA is a problem. Rest LV6.1 functionality is fine.

I used USB-RS232 converter to communicate to external device where LV6.1 was loaded on XP. I select COM port assigned number at VISA Resource Name for VISA Serial function Block. The COM Port number was selected from Device Manager which recognises my USB-RS232 converter after I connect to one of the USB port of PC which was loaded with XP. The COM & LPT Port functionality in Device Manager provides the COM port number for example COM7 or COM9 etc. Select this COM port number and Labview communicates like the regular RS232 serial Port.

Above functionality is working fine with Windows XP, but windows VISTA Home Premium doesn't works. I am unable to select the COM port number at VISA Resource Name from VISA Serial function block. This selection of VISA  resource name gets freezes and gets locked at ASRL2::INSTR. How to make VISA Serial to work? Is it a problem of Operating System VISTA ?

Vista requires a whole new set of drivers. The latest version of NI-VISA can be downloaded here

Also note that your old version of LabVIEW is unsupported on Vista as well. You may or may not run into other problems.

Also, that version of NI-VISA does not support LabVIEW 6.1. The earliest version of NI-VISA that supports Vista is 4.1, but that version of NI-VISA does not support LabVIEW 6.1 either. You will need to either upgrade LabVIEW, or use XP.

Good catch. I missed that problem entirely.

On the good side, we may have saved yet another soul from the purgatory that is otherwise known as Vista!

Equating Vista with purgatory is rating Vista much too highly and giving purgatory a bad name.
