Unable to access serial port from other application even after doing a VISA Close

[Ganeshs]

I have a LabVIEW app that accesses serial port using VISA.  While my application is running, I would like to access the same serial port with another terminal application.  So in my LV app, I put a disconnect button which calls VISA close on the session.  But this still does not allow the other app to detect COM1 as an available port.  If I close my LV app, I can then access the port from another app.

Any suggestions?

Never mind.  After VISA close, I was doing a VISA access which 'accidentally' opens the visa resource again.  I am fixing the code such that once VISA session is closed, no VISA access is done.
