Serial over Network Connector
Share serial device over IP network

Serial over Network Connector is a software solution designed to share serial ports over a network. There is no limitation as to the number of physical or virtual serial over network connections that can be managed by this software. You can share serial devices over an IP network with colleagues down the hall or across the globe. The remote connections offer the same functionality as if the devices were physically attached to the computer.
Available for Windows, Linux and Windows Mobile
Corporate, OEM & Source code
Whether you're looking at redistributing our Serial port redirection engine as a part of your product or considering Serial over Ethernet Connector software for an enterprise-wide deployment, we offer flexible and affordable corporate solutions.


Serial over Network Connector - Core Functionality

Serial over Network Connector establishes different types of connections to provide its serial port over network capabilities.

Share serial ports over network with Server connections

Server connections are created to enable the machine to share a COM port over a network. This makes the serial port and attached peripherals available to remote network-attached computers. The software allows you to create virtual serial ports that emulate all parameters and functions of a physical interface, which means that the computers that act as serial servers do not need to have actual COM ports.

Connect to shared serial ports over network with Client connections

Client connections are established from remote computers to a server. They are used to allow a client to connect to physical or virtual serial ports over Ethernet. The only configuration parameters required are the remote host’s IP address and the TCP port that will be used for the connection.

Sharing serial ports over network — distinctive features

RS232 to network software provides features that extend the serial to network capabilities of the application.

RAW data transmission

The RAW data transmission protocol can be used to transfer data over the network. This enables data to be sent without undergoing any application-layer formatting.

Runs as Windows Service

Serial over Network Connector implements serial network technology as a Windows service. Using a service enables all virtual and physical connections to be reconfigured automatically before users log in when the system is rebooted. It also allows the software’s interface to be closed after you are finished with the configuration.

Remote COM port parameters adjustment

By sharing serial to Telnet (RFC 2217), both server and client can exchange configuration details and make changes to the COM port settings involved in the communication.

COM port redirection inside a virtual session

A lack of support for serial ports in virtual environments leads to the question of how to share COM ports over the network to virtual machines. The software lets you easily redirect virtual serial ports over Ethernet to such environments as VirtualBox, Hyper-V, and VMWare virtual machines.

Smart data sending

Serial over IP software enables you to exert control over how information is sent over the established serial to network connections. You can restrict data transfer for specified time frames or until a certain amount of data has been accumulated in a buffer. Pauses can be inserted between data packets if desired.

Redirect serial data over UDP

You can select the UDP/IP protocol for transmitting serial port data over UDP. Serial over network software allows connected devices to send serial data over a local network.

FAQ about Serial over network software

There are many ways that Serial to Network Connector can be used to establish network connectivity to serial devices and applications. Some of these usage scenarios are:

  • Providing an effective method of monitoring and connecting to Modbus devices over Ethernet that are used in industrial automation systems;
  • Remotely accessing point-of-sale equipment;
  • Centrally monitoring scientific equipment located in multiple remote locations;
  • Enabling virtual environments to access network-connected serial devices;
  • Configuring network-attached serial peripheral devices remotely;
  • Connecting remotely to navigation systems and GPS applications.
Making a distinction between server and client connections is mainly done for clarity from a logical point of view. Both types of connections are essentially the same and a single connection of either type can provide access to multiple computers. In keeping with accepted commuter terminology, it is easier to think of the servers as forwarding serial ports and clients using that access to connect with the interfaces and attached devices.
Here’s how to share serial ports over a network in a few simple steps.
  • Download and install the software to the computer with the physical or virtual serial interface that needs to be shared. This machine will act as the server and provide access to remote clients.
  • Launch Serial over Network Connector on the server and choose New connection -> Server connection. In the window that will be displayed, you can identify the serial port to be used, give it a custom name, and specify the TCP port that will be used to monitor the connection. Click the “Create connection” button to continue.
  • The next step is to install the application on the client computer that will access the shared serial interface created on the server. Select New connection -> Client connection and specify the server’s IP address and the TCP port defined for the connection. At this time you can also create virtual COM ports by selecting the “Create as virtual port” option and specifying a port name.
  • Click “Create client connection”.

Once the client connection is established, it enables the client computer to access the server’s serial port and all data transmitted through it. Two-way data transmission is implemented between the virtual port on the client and the physical interface of the server.
No, there are not. You can share an unlimited number of virtual and real serial ports using Serial to Network Connector. Create as many connections as you like and have them all active at the same time with this versatile software tool.
Yes, you can. If the Internet connection is not available, you can still use LAN to transfer information between computers that are connected through Serial to Network Connector.
