On power up the active device connects to the passive device and tries to reconnect automatically if the connection is lost. If the connection is successful serial data can be passed end-to-end across the network.
Defines the port on which the serial interface can be accessed for serial gateway applications. Only when "Local port" is set to "0", the serial interface can be used as a command interface. If Destination IP is nonzero and the "Local port" is set to a value then this will be the source port of the TCP connection. If the Destination IP is nonzero and "Local port" is "0" a random source port is used. Default: "12303". 2b1af7f3a8
