Configure the gateway as the TCP (Transmission Control Protocol) Server. The TCP
Server waits for connections to be initiated by a remote TCP client device to receive
serial data. The setting allows user to specify specific TCP clients or allow any to
send serial data for serial data transmission bandwidth control and access control.
The TCP Server supports up to 128 simultaneous connections to receive serial data
from multiple TCP clients.
