Serial to Ethernet is done transparently using serial tunneling which is simple packetizing of serial data in both directions into Ethernet TCP/IP packets. This packetizing allows a user to connect a serial tunneling device to an existing serial port and have the communications go over Ethernet to another device without any software changes.
Provided is software that directs a PC COM port to Ethernet which allows the receiving end to connect to the serial device as if it were a serial cable. It is simple!
