Serial to Ethernet Connector
Virtual Serial Port over Ethernet

Serial over Ethernet Connector is able to provide any computer with multiple Ethernet serial ports together with numerous COM port devices, regardless of the number of ports the machine actually has. There is no need to have a serial port device attached to your computer directly, as you can now access a virtual COM port over Ethernet with a shared device from any place in the world. The communication data sent by the plugged COM port device is transferred across TCP/IP network and backward from the network to the serial device.
Also available on Linux OS and Windows Mobile

Sharing serial port device via Ethernet

Virtual COM Port Ethernet software enables you to effortlessly share up to 500 serial devices through network (Internet/LAN) and obtain access to a virtual serial port over Ethernet.

  • Sharing COM port for incoming connections (Server)

    Server connection, awaiting for incoming client connections, will provide a shared access to a local real or virtual COM port over Ethernet. Server connection allows multiple simultaneous client connections, where all the connected clients can transfer input/output serial data to their real or virtual serial ports, whilst Ethernet Virtual COM Port software automatically combines these multiple streams of data on server. Any application can be a client if it is capable of initializing outgoing connection to TCP/IP server (Telnet, SEC, and others).
  • Connecting COM Port to a remote computer (Client)

    Local real or virtual serial port data redirection to the remote host, using TCP/IP protocol, will begin upon creating a client connection that doesn’t require Virtual serial port to Ethernet software to be installed on the remote computer. The connection will be established once you enter the network name or IP address of the remote server and TCP port you'd like to connect to. Thus, the data sent by the remote side, will be instantly delivered to the local COM port for further processing.
  • Sharing serial port over UDP

    Using UDP/IP as a transport protocol for redirecting input/output data from your local real or virtual COM port, allows you to broadcast all the serial data via your local network without the need to install Ethernet Virtual Serial Port program on the remote end.

    With Virtual Serial Port over IP solution you can choose the data transmission protocol to be used for connection: Telnet (RFC 2217) or RAW data transmission algorithm.
  • Linux virtual serial port over Ethernet software

    Start using Serial to Ethernet Connector on Linux OS now! Assigning Linux or Windows operating systems to be a server or a client as well as broadcasting over UDP has finally become possible. Note that currently Virtual Serial Port over Ethernet for Linux OS is a command-line tool only.
