Thank You for the suggestion.

Thank You for reply. So...open port and check error string and if error string = null then port status is "opened"?

Hello! How can I check a com port state: opened/closed by using Visa Serial components? I found property: "Serial settings: Is port connected?" but when I'm trying to use it LabView says: I'll be grateful for help. BR, Artur
