I executed Serial Port application. Before this application stops execution, I am calling VISA Close to close the opened serial port. But persistance of COM Port is still available till I exit LabVIEW. Why is it so?
After closing Serial Port Application, I am able to execute other serial port access vi's in Labview. But I am not able to open the same COM Port in other applications like VB, C, Hyperterminal till I exit LabVIEW.
