TOP 5 Serial over LAN Software solutions

Olga Weis

Serial ports are still in use today, though they are not high on the priority list of modern computer manufacturers. Industrial electronic devices used for automation rely more heavily on serial interfaces than they do on the USB protocol. If you are searching for a solution for using a device that requires a COM port on your computer that only has USB interfaces, we have some answers for you. These solutions also enable serial over LAN connectivity to access devices that are remotely located.

What is serial over LAN? It is a software solution that lets you communicate with a remote COM device as if was directly connected to your computer. These software tools enable you to share serial ports over LAN as well as use serial devices with computers that are not equipped with serial ports.

Here are the top 5 serial over IP solutions to create and use virtual COM ports anywhere:

Serial to Ethernet Connector

Serial to Ethernet Connector is a robust software application that has been on the market for a number of years. Developed by Eltima Software, this application enables the creation of multiple virtual serial ports on computers that have none. It also allows serial to LAN connectivity with network attached devices located anywhere in the world.

Designed as a cross-platform solution, Serial to Ethernet Connector supports serial over LAN on Windows or on the Linux OS. This RS232 to TCP/IP converter enables the redirection of COM ports to virtual PC, Hyper-V, VMWare, etc. The application lets you create a virtual serial port pair which can then be connected to a program allowing it to communicate with serial devices or other serial-enabled software running on another network-attached computer. The parameters and functionality of physical serial ports are emulated in all of the virtual COM ports that you create and share.

Serial to Ethernet Connector supports Windows operating systems from XP (32-bit and 64-bit) to Windows 10 (32-bit and 64-bit) as well as Windows server 2012.

A Linux version is available for users of ARM-based devices.

2. TCP/Com

TCP/Com program is a basic solution suitable for accessing serial devices as well as RS232 to LAN conversion implementations. Some of the connectivity tasks it can resolve include: turning a computer into a Serial Device Server; communicate over the network with any serial device or application; enact remote control of Serial ports as if they were local; mapping of TCP/IP interfaces; split data from a single physical COM port and send it to multiple serial apps. It runs on versions of the Windows OS from 98 to Windows 10 (32- and 64-bit).


3. Network Serial Port Kit

Network Serial Port Kit is another software tool designed for COM port over LAN sharing. The serial over IP application makes a physical serial ports accessible to other network-attached computers. This lets you connect your machine to a remotely located COM device simply and easily. The program fully emulates serial port internals so that the virtual ports look and function as if they were physical ports.

Network Serial Port Kit is supported on the Windows 32- and 64-bit operating systems and lets you share and access any number of serial devices.

Serial-TCP/IP is an application that enables serial on LAN transmission and makes your current TCP/IP control software available from remote locations. Its built-in "Ping", "Resolve IP Address / HostName", "COM Port State LEDs", and "Data Logging" options facilitate analysis of your TCP/IP network and COM devices. As with the other solutions discussed, this tool makes the testing and debugging work of serial software and hardware developers easier. A limitation of this software is that it only runs on Windows 8, 7, Vista, and XP (32 and 64 bits).

5. Advanced Virtual COM port

Advanced Virtual COM Port is a communications application that offers COM port to LAN functionality as well as the ability to create virtual serial ports. Your apps will treat these ports as if they were physical interfaces as they are created with all parameters and functionality fully emulated. You can dynamically create, remove, and monitor up to 255 virtual ports with no need of rebooting your machine.

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.

Based on your requirements, one of these COM to LAN applications will solve your problem. Some of them are free, and some carry a cost. Keep in mind, that the benefit of using paid software is that you will get program updates and technical support. This can be critical in helping you use the software if you run into any potential issues. So, the decision about the app choice totally depends on your particular situation, and the requirements you have for the software performance. All these apps are a good helper in solving serial over LAN issues.

Serial to LAN hardware

Another option available in the market of serial over LAN solutions is hardware called an RS232 to LAN converter. This small device is designed to convert TCP/IP packets into Ethernet data and is also known as a serial device server or a serial port over LAN adapter. But whatever it’s called, the solution will help you establish serial communications over RS232/RS422/RS485 protocols.

When you purchase an RS232 over LAN converter, you commonly get a software driver together with a hardware device. The driver should be installed on your PC so that you can configure and control serial connections created using your COM port over LAN converter. In order to connect the hardware to your computer, the driver creates in your system a virtual serial port through which the device becomes visible to your machine.

There are a plenty of hardware SOL solutions out there and choosing the one that is right for you can be rather challenging. In order to help you make your choice, we offer a brief overview of four efficient COM to LAN adapters which are very popular today:

  • NetBurner
  • Perle solution
  • SerialLynx software
  • Lantronix

4-Port Serial to Ethernet Server by NetBurner

NetBurner Serial to Ethernet Server is a compact hardware device that can easily convert serial data into Ethernet signals and vice versa. The solution comes with a serial over LAN software utility aimed at creating virtual serial ports on a Windows computer. Both hardware and software components are fairly easy to install and use. Once you attach your serial device to a remote NetBurner server, the peripheral appears in the Device Manager of your local computer as though it were connected to the machine directly.

RS232 to Ethernet converter by Perle

RS232 to Ethernet converter by Perle is a good choice for transmitting serial data across an IP network. If you need to remotely access your serial RS232 device, Perle’s Terminal Server will come to the rescue. This solution will match the communication specifications of your equipment and offer customizable baud rates if your device requires unique baud rates.

SeriaLynx Serial-to-Ethernet Adapter

SeriaLynx Serial-to-Ethernet adapter is another handy solution that allows you to seamlessly add a serial port device to the local network. The SeriaLynx unit is equipped with two COM ports, which means you’ll be able to communicate with up to 2 wired serial devices remotely after you attach them to the SeriaLynx serial ports. Plus, the hardware will help you transmit the data across wired or wireless Ethernet.

Lantronix UDS1100 external device server

UDS1100 is a single-port device server that allows sharing RS232, RS422 and RS485 peripherals over LAN and the Internet. Thanks to the serial tunneling capability, UDS1100 can encapsulate serial data into packets and transport it over Ethernet fast and reliably. What’s especially convenient is that users can access and configure UDS1100 from a standard web browser, as the solution offers a built-in web server.
