SocketServer Overview
Serial tunneling mode is used to establish a socket connection between two
DeviceMaster AIR units through an ethernet network.
UDP mode is designed for applications that need faster data transmission, or that
make use of UDP’s broadcast capabilities. UDP differs from TCP in that a UDP
transmission does not first require a connection to be opened before sending data
and the receiving device does not issue acknowledgements to the sender.
