When working with serial interfaces and network protocols it is very likely that you will need to employ a specialized tool. The tool is called a serial to Ethernet adapter and is also known as a device server, a serial extender, or a serial over Ethernet connector. The extender is used to convert serial port transmissions into TCP/IP data. It allows users to access and control remote serial ports without the need for physical proximity. Use of a COM port extender enables any network-attached serial interface to be shared and accessed across the network.
