  • cncrn.png TCP connection —

    TCP connection specifies the network connection reference that uniquely identifies the TCP connection.

  • ibool.png TLS? —

    TLS? returns TRUE when TCP connection is encrypted with TLS; returns FALSE when TCP connection is closed, invalid, or is not encrypted with TLS.

    • Note LabVIEW may close TCP connection of its own accord if an error occurs during Start TLS or Accept TLS.
