Serial over IP best solutions - RS232 to IP software TOP 5

Olga Weis

A quick look at most modern computers would give the impression that there is no need to support serial devices as no serial ports are built into the machines. This is not the case, as serial interfaces are used more often in industry than are USB ports. Industrial automation makes widespread use of serial devices to monitor and control various production processes. There are also many situations where having the ability to access your serial devices remotely over a network is required and can make better use of your hardware resources.

If you need to use a serial device on a computer with no COM interfaces or want to access serial devices that are located remotely, there is a Serial over IP Connector technology that should be able to resolve your connectivity issues. Serial over IP Connector is a specialized software or hardware solution for connecting remote networked devices with a COM port interface over Ethernet.

COM over IP software tools we will be looking at address the problem caused by the lack of a serial interface on your computer. These applications also allow you to share serial ports over IP and access remote devices as if they were locally attached. This facility can save you time and money as expensive peripherals can easily be shared over a network rather than being swapped back and forth to different computers. It also makes monitoring the serial devices of a complete production operation possible from a single computer, simplifying the jobs of your IT staff.

Top 5 RS232 over IP tools for creating and accessing virtual COM ports via an IP network:


  1. Serial to Ethernet Connector
  2. TCP/Com
  4. Advanced Virtual COM port
  5. Network Serial Port Kit

1. Serial to Ethernet Connector

Serial to Ethernet Connector is a comprehensive and professional serial over IP software application developed by Eltima Software that has been on the market for a number of years. This means you are getting a quality product that has been used in many scenarios and tested by multiple users. By using this software tool you can create virtual COM interfaces on your machine as well as access and share serial ports over TCP/IP remotely. Communication between network-attached serial devices and your computer is possible with this application. You can create an unlimited number of virtual ports depending on the capabilities of your computer system.

Serial to Ethernet Connector

This is a versatile solution due to the fact that this serial over IP connector software application is supported on both the Windows and Linux operating systems. COM port traffic can be redirected to virtual environments such as virtual PC, Hyper-V, and VMWare with this RS232 to TCP/IP software adapter.

You can use this software tool to create pairs of virtual COM ports over IP network. These can then be connected to serial devices or other applications that reside on the same network. Hardware interfaces are fully emulated so you can be sure of device and application compatibility when sharing serial over IP network. Your programs will treat the virtual interfaces as if they were physical ports and you will notice no difference in performance.

Serial to Ethernet Connector is supported on all Windows systems from XP (32-bit and 64-bit) to Windows 10 (32-bit and 64-bit). It will also run on Windows server 2016.

There is a Linux version available for users with ARM-based devices.

2. TCP/Com

TCP/Com is a basic software solution that helps resolve a number of serial and network conversion and connectivity issues. Some of the uses of this RS232 to IP software include modifying your computer to make it a Serial Device Server, remote access and control of serial ports, and mapping between TCP/IP interfaces. It also allows you to communicate over the network with any serial applications and lets you send data received from one physical COM port to any number of serial apps. TCP/Com run on Windows systems from 98 to Win 10 on both the 32 and 64 bit flavors.



This application extends the reach of your serial communication by employing your network and makes your current network control software and all other serial applications available from any location. Serial-TCP/IP has built-in options that let you perform tasks such as pinging, logging data, and resolving IP addresses that help in analyzing your network. As with all of these software tools, those developers working with serial hardware or software products will benefit from their facility for testing and debugging. If you need to share serial devices over IP network, this program will work for you if are using Windows 8, 7, Vista, or XP (32 and 64 bits).

4. Advanced Virtual COM port

Advanced Virtual COM Port is another software tool that allows you to share RS232 over IP as well as creating virtual ports on your computer. Any serial application will work perfectly with the virtual interfaces as they fully emulate the functionality of hardware ports. It offers the ability for dynamic creation and removal of virtual serial ports without the need to reboot your machine. Up to 255 virtual ports can be created and monitored simultaneously with this tool. It lets you use computers with no COM ports to access serial devices with no additional hardware requirements.

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.

5. Network Serial Port Kit

Another program that lets you share COM port data over IP is Network Serial Port Kit. The application makes physical serial ports available to network-attached machines and enables you to share serial interfaces locally or over the network. With this tool connecting remote serial devices is an easy task. The program also emulates physical serial ports and lets you share virtual serial ports over IP. This ensures that they interact well with your serial applications as they have the identical functionality of hardware ports. The ability to create virtual serial ports lets you use serial devices with any computer, no matter what kind of interfaces it contains.

An unlimited number of serial devices can be accessed and shared with Network Serial Port Kit which runs on the Windows OS 32- and 64-bit versions.

Based on your particular situation, one of these applications may work for you when you require serial port over IP connectivity. This can be important in industrial automation systems and many other production control installations. They can also make serial devices accessible from any computer with the ability to create virtual interfaces that emulate a hardware port.

Some of these apps are free and some require a monetary investment. When choosing the solution that you intend to use, consider that a paid software product includes technical support that can help you resolve any issues when implementing the product. Program updates are also included with paid software and these can be instrumental in keeping your machine secure and taking advantage of new features added to the applications.
