Serial port redirector software - redirect COM data over Ethernet

Olga Weis

Working with serial devices is often not an easy task. Most modern computers are not equipped with serial ports, while a lot of applications, especially industrial software, still require them to communicate with devices. So what do you do if you have an app that needs to talk to a serial device, and your computer has no serial ports? Don’t worry, as long as there is at least one machine in your network that has an interface for serial communication, this is not an issue. Insert the device into that computer and redirect COM data to the application installed on your local machine – you can use either serial port redirector software or additional hardware to do it. We’ll talk about them below.

Best COM port redirector software

Serial to Ethernet Connector by Eltima Software

Eltima Software already has the solution to redirect serial port data - Serial to Ethernet Connector. RS232 port redirection means that you can share a local serial port and device connected to it with other network users, and, in turn, access a port on a remote computer.

RS232 port redirection hardware

Install Serial to Ethernet Connector to use the content and functionality of remote devices as if they were attached to your local machine. The physical proximity to the device – across the office cubicle or across the globe – doesn’t really matter.

How to use Serial to Ethernet Connector:

  1. Download the COM port redirector and install it on a computer that provides shared access to their devices (server) and a computer that needs the remote access (client).
    If you want to reach ports from virtual machines, make sure to install the software on guest OS.
  2. Launch the app on the server, select ‘Create Server Connection’ option and set up required parameters.
  3. Open the app on a client machine and configure the connection there.

That’s it – now you can access a remote device over network and interact with it as if it were a local device.

The serial port redirector is compatible with Windows and Linux operating systems. Linux version is now available as a command-line app.

Serial Port Redirector by FabulaTech

Serial Port Redirector is a dedicated software designed to redirect COM port data over TCP/IP network. If your computer lacks physical COM ports, this solution will easily help you create virtual serial interfaces in your system. The advantage of the program is its ability to transport raw serial data over the network. What’s more, this RS232 port redirection app can connect to COM port servers over RFC2217 protocol.

Key features of Virtual Serial Port Redirector:

  • Enabling network communications between serial apps.
  • Creating highly configurable virtual COM ports.
  • Establishing connections between real and virtual COM interfaces.
  • Complete emulation of physical COM port parameters and behavior.
  • Support for Telnet RFC2217 protocol.

Com Port Redirector by Lantronix

Com Port Redirector is an advanced software for sharing serial ports across the network. The solution is able to map virtual serial port on a PC platform. Thanks to this efficient tool, you can provide your timing sensitive serial applications with the ability to exchange data with remote devices over Ethernet. Additionally to data transmission, this useful COM port redirector utility will allow you to control and monitor the activity of remote networked equipment.

Key features of Virtual Com Port Redirector:

  • Controlling COM-based equipment over the network.
  • Sniffing the activity of redirected ports.
  • Monitoring signal line control.
  • Working over any distance.
  • Providing data exchange between serial applications and any remote equipment.

All you have to do is to insert a device into a serial port and then connect it to Ethernet. This doesn’t require any software or setup, but you are restricted by physical distance to a device – cables are not infinitely stretchable, as we know. Often, even if the distance is not really significant, there might be physical obstacles such as windows and walls.

Comparing all of these software and hardware tools, we’d rather go for the Serial to Ethernet Connector software that enables redirecting serial data over network at any distance and provides a host of advanced features to make RS232 port redirection easy and effortless.
