You can share a serial device over LAN with the help of a software or hardware solution. In this tutorial, we’ll tell you about the top RS232 over LAN apps and their main advantages.

1. Serial to Ethernet Connector

The first place in our list of the best serial over LAN solutions takes Serial over Ethernet Connector by Electronic Team. The solution has proved to be extremely efficient in sharing serial interfaces over the network. It allows creating virtual copies of physical COM ports, which means you can provide your system with as many serial interfaces as you need. Even if you don’t have a single hardware COM port in your PC, this software will help you establish a connection to a remote serial port and a device plugged into it as though the device were attached directly to your computer.

If you are looking for an easy way to share serial port over LAN, just install Serial over Ethernet Connector on the server and client sides of your healthcare device network. Easily access and manage any remote RS232 devices over LAN as if they were your local devices.

Serial to Ethernet Connector

Serial to Ethernet software consists of the server and client parts. The server component will let you share local real and virtual COM ports with multiple remote clients while the client-side component will allow you to initialize a connection to the TCP/IP server. In order to create a client connection, you simply specify the hostname of the remote server and a TCP port to connect to.

The key benefits you get with this SOL solution:

  • The ability to create an unlimited number of virtual serial ports.
  • The possibility to exchange serial data over the UDP protocol. What’s nice is that in this case, you don’t need to have Serial to Ethernet Connector installed on the remote PC.
  • The possibility to select RAW data transmission algorithm or Telnet (RFC 2217) protocol for data transfer.
  • The application works as a Windows service, so after you reboot your system all connections and settings will be re-configured automatically.
  • Serial to Ethernet Connector supports different Windows versions (x32 and x64), including Windows XP/2003/2008/Vista/7/8/10/11 on ARM, Windows Server 2012/2016/2019/2022. In addition, you get the ability to use a command-line software version for Linux OS.

2. FlexiHub

FlexiHub is another popular software application for serial port remote access. This powerful utility also works as a Windows service and allows you to share COM ports over LAN and any distance.

The software is powered by an advanced port redirection technology which makes it possible to virtualize any COM port over LAN and forward it to a user’s local computer. The app has a streamlined and intuitive GUI and can be run as by tech-savvy users as by computer newbies.


The clear advantages of FlexiHub as an RS232 extender software:

  • It lets you share both COM and USB interfaces together with devices plugged into them. Remote users will be able to access the devices inserted into your local computer like the peripherals were connected to their machines.
  • You can choose an individual subscription plan depending on the number of connections you need.
  • FlexiHub provides a convenient traffic compression option which helps increase the speed of your network communications.
  • All data transported over the network is protected with advanced encryption.
  • While sharing and accessing USB and COM peripherals over LAN, you can interact with remote users via FlexiChat.


TCP/COM is a simple yet functional utility that will help you cope with a wide variety of serial to network conversion tasks. This program comes in handy for exchanging RS232 data with any serial app over a TCP/IP connection. In fact, the software lets you use your local computer as a serial to Ethernet adapter, which means you’ll be able to initialize connections to remote COM port devices and access them to LAN as though they were inserted right into your local machine.


4. Network Serial Port Kit

Network Serial Port Kit will allow you to share real and virtual serial ports over LAN or the Internet in such a way that they will become available for connection from other PCs over the network. To virtualize a real COM port using Network Serial Port Kit, you need to install the software on both machines: the one with the hardware interface and the one that will connect to this port remotely.

Now, when you share the hardware port on the machine where it’s physically present, the software creates a virtual copy of this port on the remote computer. As soon as your RS232 app opens the virtual port, the connection between the real and virtual serial ports is created and all data received by the virtual interface gets sent to the physical serial port and backwards.

Network Serial Port Kit


SERIAL-TCP/IP program will be a good choice for those who are building their own TCP/COM control apps. The software makes it possible to establish serial communications via the TCP/IP channel. So, you’ll be able to analyze your network connections, test and debug COM-based devices and software. SERIAL-TCP/IP solution has the advanced "Ping", "COM Port State LEDs", and "Data Logging" features and is compatible with Windows 8, 7, Vista, and XP (x32 and x64) versions.

6. Advanced Virtual COM port

Looking for a decent serial over LAN software you would probably want it to meet a list of your requirements. If you need a solution capable of providing your system with a big number of virtual serial ports that will work exactly like the real ones, the following app will be great for you. Advanced Virtual COM port is a simple utility with powerful functionality. Once you create a virtual RS232 port with this program, the interface will exist in your system until you delete it. What’s good about the app is that it lets you create and delete virtual ports with no need to reboot your PC.
