Serial port over IP 2020 guide - How to access RS232 over TCP/IP

When we talk about IP networking, some might think we only talk about the Internet. True, IP stands for Internet Protocol, but any network can utilize this protocol to transfer data between computers. Thus local area networks (LAN) and enterprise networks fall into this category too. In an IP network all nodes need to be configured with the TCP/IP suite.

This protocol allows sending and receiving data in a number of ways, and this includes accessing remote ports in the network – see below.

Share serial port over IP network

Serial over IP software (“SOI” for short) is a technology developed for users who are looking for a way of sharing serial port data (such as RS232s, RS422s, or RS485s) across multiple devices via an IP network. Serial over IP can be used with systems (such as Blade Servers) in order to access the Blade Server’s programs by way of a COM port.

If you want to control your RS232 over IP, as well as how to conveniently manage their ports and other systems, keep reading.

How to access remote serial port over IP

We often come across situations when we need to use serial devices, which we cannot access physically, they could be located at a long distance from us or it’s just not feasible to connect to it.

Users might find themselves in need of the ability to gain access to a “serial-based peripheral device”(such as SD cards, sensors, and shift registers) remotely, as their SPI(serial port interface) is not within physical proximity to their computer system.

Through the implementation of a serial over IP adapter. Using a serial over IP adapter lets users convert data transmissions from COM to IP format.

Special software application – Serial to Ethernet Connector - will help to work with serial port over IP. With the app you are free to access RS232 over TCP/IP network without any limitations.

A serial over IP adapter can come in both software and hardware options, but regardless of which option you choose the translation occurs by data being sent via a COM port and to a TCP/IP format. Now users can easily transmit data over an IP-based network (like the internet).

Users could experience multiple scenarios where they require the ability to commute data over an IP network. For example, situations involving routing RS232 traffic via IP is helpful for users working with industrial automation, POS(Point Of Sale) devices, as well as many other equipment types.

Utilizing serial over IP protocol technology lets users remotely access a serial device with the same responsiveness that they would expect if the device was directly plugged into their computer.

It allows to work with serial ports remotely, e.g. to access serial port over Internet or share serial port over IP, etc., so you can use devices connected to them as if they were inserted locally. The actual distance does not really matter – the device can be attached to a computer across your cubicle or across the globe, the way they become accessible to us is just the same.

This TCP/IP Conversion Software Has A Multitude Of Uses, Including:

  • Providing users with the ability to connect with serial ports from virtual environments like VirtualBox, VMware, and Hyper-V
  • Share COM ports on multiple computers and devices that run on Windows, Linux, and ARM operating systems
  • The Ability to transmit RAW data
  • Easily redirect serial traffic via UDP/IP, regardless of whether it is real or virtual

Users don’t have to worry about distance impacting their workflow. When implementing a Serial over Ethernet Connector(SEC), factors such as the location of a specific device that they want to connect to doesn’t matter.

All the user needs to do is install the easy-to-use SEC software on both the computer physically connected to the device, as well as the computer that the user wishes to access the device from remotely.

Share serial over IP

The way Serial to Ethernet Connector (SEC) works is pretty simple – once installed on the local and remote machines it creates a virtual bridge between them so they can talk to each other. This serial over IP software enables network users to access the contents or functionality of a remote serial device as if it were inserted directly into your machine.

Here ‘Server’ is a machine that shares serial over TCP IP, while ‘Client’ is a machine that needs to access serial port over TCP IP.

Your step-by-step guide on how to use Serial to Ethernet Connector:

  1. Download and install the application on the computers that need to share and access serial port over IP (this can include virtual machines too).
  2. Launch the app on the server and choose ‘Create Server Connection’ in the menu, setup the connection parameters. Share a required serial over IP.
  3. Launch the app on the client and choose ‘Create Client Connection’ in the menu, configure the connection.
  4. Once you connect to the port, you can start using a device inserted into it right away.

Serial to Ethernet Connector supports Windows and Linux, the latter version is currently a command-line app.

Sharing Serial Over IP Traffic On Linux OS

Pretty much every modern Linux distros all have native capabilities that allow users to enable communications via a remote serial interface.

For users who are interested in establishing a serial over IP on Linux machines, you can use a utility called a NetCat Procedure. Users will be required to run a new instance of Netcat for each connection that they intend to establish.

Users can also build a “persistent connection” when they implement a “xinetd” service consisting of the following configuration.

{ port = 5900

socket_type = stream

protocol = tcp

wait = yes

user = root

server = /usr/bin/netcat

server_args = "-l 5900 < /dev/ttyS0" }

Users must change the name of the /dev/ttyS0 parameter to the same name as the serial device that the user intends to connect. In order to configure serial port parameters like Parity and Baud Rate, use the “stty” or “setserial” commands.
