Best Serial port Redirector solutions

Despite the fact that serial interfaces are not generally standard equipment on modern computers, many devices that use serial ports are still in use. Industrial applications favor serial interfaces over the more commonly seen USB ports. If you are in need of a way to use serial devices with a computer that is not equipped with any serial interfaces, we have some solutions you can try. These serial port redirector applications will also let you remotely access and control a network-attached serial device.

Computers without physical serial ports or machines housed in remote locations can access and redirect serial devices over the network by using COM port redirector software. Using a RS232 redirector, remote devices will appear as if they are attached directly to your machine.

The top 5 serial redirector software solutions for creating and accessing virtual COM ports:


  1. Serial to Ethernet Connector
  2. TCP/Com
  3. Network Serial Port Kit
  5. Advanced Virtual COM port
  6. COM Port Redirector
  7. Hardware serial port redirector

1. Serial to Ethernet Connector

Serial to Ethernet Connector is a stable software product developed by Eltima Software and has been available commercially for over a decade. The application lets you create multiple virtual COM ports on a machine with no physical serial interfaces. This virtual serial port redirector enables you to access the functionality of multiple remote serial devices over the network. You system’s capabilities are the only limit on the number of virtual ports you can create with this COM port redirector utility. It transmits serial data over the Ethernet from your computer to network-attached serial devices.

Serial to Ethernet Connector

Serial to Ethernet Connector is a versatile, cross-platform application that runs on both the Windows and Linux operating systems. Redirection of serial ports can be done on virtual PC, Hyper-V, VMWare, and other virtual platforms using this virtual com port redirector. You can create virtual serial port pairs with the program. These ports can be connected to network-attached serial devices or serial software using this RS485 redirector. The virtual interfaces you create fully emulate the functionality of the physical ports so your applications work with them as if they were a real port.

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.

Serial port redirector supports Windows systems from XP (32-bit and 64-bit) to Windows 10 (32-bit and 64-bit) and Windows server 2012, and Linux operating systems. Linux version is now available as a command-line app.

Those users with ARM computers can use the Linux version available for ARM-based devices.

2. TCP/Com

TCP/Com is a basic and versatile program that can solve a number of issues you may face when required to connect devices or redirect serial port transmission over the network. It can be used to assist in a variety of TCP communication processes. Some examples include the ability to turn your machine into a Serial Device Server, communicate over the network with any COM device or serial application, and map serial ports. It can also be used to access remote serial ports as if they were locally attached and send data received from a single physical port to multiple serial programs.

TCP/Com supports versions of the Windows operating system from 98 to Windows 10 (32- and 64-bit).


3. Network Serial Port Kit

Network Serial Port Kit is an application that can be used to redirect COM data over the network and facilitates the sharing of serial devices whether locally or remotely located.

Network availability of a physical serial port is possible with this serial over IP software. Remote devices can easily be connected with this Ethernet COM port redirector application. All of the virtual serial interfaces that are created fully emulate the functionality of the physical COM ports ensuring that your programs use them seamlessly.

Network Serial Port Kit allows you to share and access unlimited serial devices and is supported on the Windows OS 32- and 64-bit.

Serial-TCP/IP is a program that serves as a TCP serial port redirector enabling you to access your current control systems remotely. It features built-in "Ping", "Resolve IP Address / HostName", "COM Port State LEDs", and "Data Logging" options that simplify the analysis of your TCP/IP network. As with the other software products we are looking at, this is a great tool for the debugging and testing of serial software and hardware products. Unfortunately, this program only runs on Windows 8, 7, Vista, and XP (32 and 64 bits).

5. Advanced Virtual COM port

Advanced Virtual COM Port is an application that offers features designed to enable the creation and use of network and local virtual serial interfaces. This program fully emulates hardware ports in the creation of virtual interfaces so your applications will not experience any unpleasant issues when using them. Hot creation and removal of ports is possible without the need to reboot your machine. The tool allows the creation and monitoring of up to 255 virtual serial interfaces.

Advanced Virtual COM port supports Windows 2000 - Windows 8.1 (32 and 64-bit) and Windows Server 2012 R2. It also supports Windows CE versions: CE 5.0 (x86), CE 5.0 - 6.0 (arm), Mobile 2003 SE, and Mobile 5.0 - 6.5.

6. COM Port Redirector

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.

Based on your specific requirements one of these RS232 port redirector applications may be just what you need. Though there are free options available, when you purchase a paid software tool you receive the benefits of technical support and product updates. This can be instrumental in resolving any issues you may have when implementing the software.

7. Hardware serial port redirector

Serial Port Redirector Software

It is relatively easy to set up a hardware RS232 redirector. 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.
