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.

Frequently asked question

A virtual COM port is a software emulation of a physical COM interface. Also known as a virtual serial port, it is used to connect legacy serial software programs on computers that don’t have any physical serial interfaces. In the absence of real COM ports, a virtual serial port emulator can send serial data over an IP-based network. This replicates the functionality of the missing physical port. Data sent from the legacy serial application is transmitted over the network through the virtual port. The same process of using a virtual serial port over Ethernet is used to return information to the legacy program. A virtual interface allows two-way serial traffic on computers that lack real serial ports.
At one time, the majority of computers were equipped with several RS-232 serial ports. These were used to establish direct, physical connections to serial-based hardware such as laboratory equipment, industrial machinery, and other peripheral devices. This is no longer the case, as computer manufacturers now choose to include other types of connectivity options like USB ports. Most modern laptops have no serial ports and desktop machines have a limited number of them at best.
The same virtualization technology that allows you to access serial devices without a COM port lets you establish RS232 over IP connectivity to network-attached equipment. Once connected, you have the same level of control over the device as if it was directly connected to your computer. Serial over Ethernet Connector can be used in many scenarios to enable network communication between your serial devices.
Serial to Ethernet Connector has no distance limitations, making it possible to connect virtual serial ports over Ethernet no matter where they are physically located. Simply install the application on the machine with a direct connection to the device and all remote client computers that need access to it. Your IP network is then used to allow the clients to remotely access and control the devices.
Linux users can also take advantage of the capacities of Serial to Ethernet Connector. All of the functionality afforded to Windows users is replicated in the Linux version of this virtualization software which can be downloaded to any Linux machine.

In addition to using Serial to Ethernet Connector, there are native methods available on most modern distributions that allow you to set up a free virtual serial port over Ethernet.
