Serial device server is a network device that transfers data between an Ethernet LAN and a serial port (COM port) of a computer or device. The main purpose of the serial device server is to allow serial devices such as printers, scanners or climate control systems to be used in the network without relying on the serial port of the computer. This allows any serial device to connect to the network and access it from anywhere, including from the Internet.}
