configure additional settings, including TCP alive check time, TCP port, Packet length, Delimiter 1,

alive” packets.
0: The TCP connection will remain open even if there is no response to the “keep alive”
packets.
1 to 99: If the remote host does not respond to the packet within the specified time, the
NPort will force the existing TCP connection to close.

and that other devices must use to contact the serial port.
