Access serial port over IP network


Many people who work with serial devices think that one of the worst things about using them is the inability to access them remotely. And that may be true but just if you don’t have a dedicated software or hardware to share serial over IP network. Now, specialized tools can help you forward serial equipment securely to the remote server system in another building or easily redirect it to the virtual environment or a blade server. And not only that but wouldn’t it be great to be able to connect to COM devices over the Internet with full access to their contents and functionality even when you are in the other part of the world? If you want this, you aren’t exactly spoiled for choice of solutions that may come in handy.

In this article, we’ll tell you about the most common software and hardware methods to share serial port over TCP/IP network so that you can see their pros and cons and choose the way that will be right for you.

FlexiHub: Serial to IP Software


FlexiHub is easily one of the best products to ever come out of Eltima Software. It brings the functionality of a full-fledged serial over IP redirector without any of the hassles. Because FlexiHub goes beyond what other serial to IP apps are able to offer, especially with regard to the speed of connections and security of data transfer, the software seems to be the most efficient way to share serial devices for remote access.

The program works over Ethernet, any local network, WiFi and the Internet. As a result, the user can reach a serial device from a remote location and doesn’t really have to worry about where the device is located physically.

The main reasons why you should choose FlexiHub to share serial over IP:

  • Friendly and intuitive interface. The app is extremely simple to install and use.
  • It’s up to you to choose the maximum number of remote devices that can be connected to your PC at a time.
  • You can lock your local serial device at any moment and other users won’t see it.
  • The software works over any distance with nearly any type of serial devices and ports (RS232, RS422, RS485)
  • Additionally to serial interfaces, you’ll be able to work with USB ports as well.

FlexiHub is a winning product for both those who want to share their local serial devices among other users and those who need to access remote COM ports over the Internet.

Here’s how exactly the serial over IP software works:


  1. The first step, you register your FlexiHub account and install the app an all machines that will work with the required serial device including the one (server) where the device is attached physically.
  2. The second step, you start the utility on the server machine and log into the FlexiHub account.
  3. The third step, you run the app on the PC that needs to access the device remotely and log into the software account using the same credentials. When you see the list of remote serial peripherals, all you’ll need to do is click “Connect” next to the required device.

Hardware method


Alternatively, you can try using a dedicated hardware to share serial over TCP/IP. Standard serial over IP extenders (also known as terminal or device servers) will let you transform asynchronous serial signals into TCP or UDP packets and send them over the network. Is that going to be enough to share your devices for remote access? Probably yes, but you should remember that the hardware works well for short distances, for example, between computers that are located in the same room. If PCs are far from each other or there is something that blocks the way, remote access to a serial device will become a real challenge.

Another difference that you need to understand is that traditional serial over IP extenders come with a limited number of serial interfaces whereas a software tool allows working with as many COM ports as you need.
