Eltima Serial to Ethernet Connector allows you to share up to 255 serial port devices over TCP/IP network turning your computer into low-cost terminal server. As the result, any serial port device connected to COM port could be accessed from anywhere in the world as if it is attached to local PC. When the attached serial port device sends communication data it will be actually transmitted over TCP/IP network. Such behavior is achieved due to the use of virtual serial port technology which emulates standard COM ports. In that case Windows OS treats virtual serial ports in the same way as real ones therefore you are no longer limited to just two real ports (any number of physical ports you have) per system and may create COM port connections without occupying any real serial port. Serial to Ethernet Connector provides the ability create several connection types for three main purposes: share serial port for incoming connections (Server), connect serial port to remote host (Client) and share serial port using UDP. Starting from version 4.0 Serial to Ethernet Connector enables you to select data transmission protocol, which will be used for connection: RAW data transmission algorithm or Telnet (RFC 2217) protocol.
