How to refresh visa resource list

$

Hi,

 

I have a device connected on COM4 of the system. Initially LabVIEW finds it. Then I send a RESET command (VISA write) to this device connected on COM4. As a result of the RESETcommand, the COM4 momentarily closes and reopens. But when it reopens, LabVIEW is not able to find COM4, as shown in the first picture below. The second picture below is my block diagram where I am trying to find COM4, so that when COM4 re-appears, I can proceed with sending other commands to this device. The third picture shows, that when COM4 does reappear (after closing first), the OS is able to find it but LabVIEW does not (in the first picture).

 

The question is, How can I have LabVIEW refresh and find COM4 in the VISA resources list?

Thanks

Jeet
