A Smarter Way to Redirect COM Port Traffic for Reliable Device Connections

The best way to redirect your Serial port device

In many factories and industrial settings, older machines still use COM ports to communicate. You might be working with RS232 devices, MODBUS controllers, or GPS equipment. Being able to redirect this COM port traffic lets you access devices from anywhere, makes troubleshooting easier, and helps everything work together smoothly on a modern network.

Why Redirect COM Port Traffic?

COM port redirecting helps you do several useful things:

  • Connect to serial devices from anywhere using a network.
  • Create virtual COM ports for applications that require a physical hardware connection.
  • Resolve issues when several programs need to access one port simultaneously.
  • Use old equipment with new computer systems.

This is very helpful when you cannot easily reach the equipment or when several programs need to use the same serial device.

How to Redirect COM Ports

You can redirect COM ports in two main ways:

1. Software Tools

These are applications that create virtual COM ports on your computer and transmit their data across your network or over the internet. They often let you do things like:

  • Create virtual COM ports
  • Send data over your network (TCP/IP)
  • Watch and save the data that passes through
  • Work on both Windows and Linux computers

Companies like AGG Software make tools such as the Advanced Serial Data Logger and Virtual Null Modem. These let you easily redirect and watch your COM port data between different computers.

2. Hardware Device Servers

These are physical devices where you connect your serial equipment. The device server then links your serial device directly to your local network. While these units are very dependable, they tend to be more expensive and less adaptable than software solutions.

A Simple Guide to Software Setup

Here are the basic steps to get a COM Port Redirector working:

  1. First, install the redirection software on the computer that has the real serial device plugged into it (this is called the server).
  2. In the software, create a “server connection.” Pick the real COM port you want to share.
  3. Now, enter the network information. You will need the IP address and a port number. Then, choose how to send the data. Two common ways are Raw TCP or Telnet.
  4. On the second computer, the one that will use the device, install the same program.
  5. In the program, make a new virtual COM port and connect it to the server computer address you saved earlier.
  6. Now it’s time to see if everything is connected properly. Open a basic terminal program and type a short test message.
  7. If you see that same message show up on the other computer, then you’ll know your connection is good to go.

Once this is done, the client computer can use the remote serial device just like it was plugged in directly.

A Good Tool for the Job

If you need a steady and flexible way to redirect COM port traffic, take a look at AGG Software’s tools. Their tools, like Virtual Null Modem and TCP Splitter, are trusted by many IT experts and technicians. These programs help you share data quickly, create virtual ports, and connect with devices that use common industrial systems.

If you are fixing old machines or building new ones, AGG Software offers easy menus and strong tools that make your job simple.

Where COM Port Redirecting is Used

You’ll find this technology hard at work in many fields:

  • On the factory floor, it links production machines and sensors back to a central control room computer.
  • For telecom companies, it gives technicians a way to monitor network equipment from a remote location.
  • In transportation, it takes GPS data from vehicles and feeds it into live tracking maps.
  • At water and power companies, this technology connects older meters and gauges to new, modern monitoring systems.

Conclusion

Using COM port redirection is a clever method for giving older equipment new life. The right software tools help technicians link their trusted old devices to modern networks. This allows them to continue using their familiar hardware while gaining the benefits of a modern setup, all without sacrificing performance or dependability.
