Best TCP COM software to share serial
over Ethernet

Olga Weis

In the modern world serial devices are tucked in the back of computer vendors priorities. However this doesn't mean serial ports are not in use anymore. On the contrary, industrial divisions work with serial ports much more often than USB. So if you are currently trying to find the answer to the question of what to do if your computer doesn't have a COM port and you need to use device that can only be connected with this type of port or if a serial device you want to use is located far from your computer, we've got the answer!

Even if you don't have a port on your local computer to connect device to or the device cannot be connected due to remote location you can share serial port over IP with a special software and use the device as if it was attached to your computer.

Top 5 serial over IP solutions to create and use virtual COM port anywhere:


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

1. Serial to Ethernet Connector

Serial to Ethernet Connector is developed by Eltima Software and has been on the market for many years, which means a polished product. With this program your computer can have multiple serial ports even if in reality it has none and you can work with multiple serial devices over IP even if they are located overseas. In fact the number of virtual ports can be unlimited, depending on your system's capabilities. Serial communication data is transmitted over TCP/IP network and from the network to your serial device.

Serial to Ethernet Connector supports Windows and Linux operating systems which makes this solution cross-platform. One can redirect serial ports to virtual PC, Hyper-V, VMWare, etc. with this RS232 to TCP IP converter. This serial over Ethernet software allows you to create virtual COM port pair, connect a program to it that can work with a serial device or even another program on a remote computer on the network. All created and shared virtual COM ports behave the same way as real ones would and apps working with them treat them no different than physical ports.

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

For those using ARM computers there is a Linux version for ARM-based devices.

2. TCP/Com

TCP/Com program is a simple solution that can be used for a variety of device interfacing and RS232 or TCP/IP conversion issues. For example it helps with the following TCP COM tasks: you can turn a computer into a Serial Device Server; send/receive information over a TCP/IP with any serial app; open COM ports on a remote computer as if they were local ones; send data from a physical RS232 port to multiple RS232 serial apps; map one TCP/IP port to another. TCP/Com supports Windows systems from 98 to Win 10 (32- and 64-bit).


3. Network Serial Port Kit

Network Serial Port Kit is another serial over LAN software for serial ports and COM port devices sharing over Internet or locally. Thanks to this serial over IP software a physical port becomes accessible for other computers over network. As a result you can connect to a remote serial device from anywhere with a minimal effort. Virtual serial ports will look and behave the same way as physical COM ports as the app fully emulates COM port internals.

Network Serial Port Kit allows sharing and accessing an unlimited number of serial devices and supports Windows OS 32- and 64-bit.

Serial-TCP/IP program can extend serial communication distance via TCP/IP; makes your existing TCP/IP control software accessible over the distance; allows analyzing TCP/IP and COM network with its built-in "Ping", "Resolve IP Address / HostName", "COM Port State LEDs", and "Data Logging" options. Just like the previously mentioned software solutions, this app is a handy tool for developers of serial software and hardware manufacturers, allowing them to test and debug their projects. This software only works for Windows 8, 7, Vista, and XP (32 and
64 bits) though.

5. Advanced Virtual COM port

Advanced Virtual COM Port is a serial communications software offering network and local virtual COM port features. The virtual COM ports this app creates behave just like the physical ports, so the apps working with them have no conflicts and treat them as they would treat hardware ports. One can use hot creation and removal of ports without rebooting computer. You can create up to 255 virtual ports and monitor the ports' states easily.

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.

Depending on your needs you can try and choose one of the overviewed software. Some programs are free, some require an investment. Remember that when you are investing in a software solution you are getting constant updates and dedicated tech support that will help you resolve any possible issues you might experience while using the software.
