Does "VISA Read" still try to read from serial port even if after VISA Close?

Of course. For several years, VISA Open and VISA Close have been completely optional. If a session does not exist, it will be automatically created by VISA Write, Read, etc.

Thank you! I'm new to LabVIEW. Is there any VISA operation to stop the VISA Read after VISA Close?
