Working with serial port data are essential tasks when working with serial devices and applications. You need the ability to observe the flow of data through RS232/422/485 ports to verify the status of a device, receive event notifications, and identify problems with your infrastructure. Monitoring serial port traffic can also be very helpful when you are installing new equipment.
There is no built-in facility in the Windows operating system to monitor serial ports, but there is specialized RS232 monitor software which allows you to conduct Windows serial port monitoring.
Eltima Software’s Serial Port Analyzer fills this gap in Windows functionality. It is a serial port monitor that offers a convenient method of observing your system’s serial traffic. Developers can easily monitor and test a serial port during the development and optimization of serial devices and applications. We will show you how to monitor COM port transmission in the article.
To monitor and analyze serial data, COM port monitor offers three ways to solve this problem:
The first step is to download, install, and launch RS232 protocol analyzer. Next, you need to start a new session in the serial monitoring software. Here’s how it is done:
Comparing the results from two different monitoring sessions enables you to gain valuable insight into the functionality of your serial communication.
After you have analyzed a serial data and saved the session, you can compare it to another session to identify the differences by using Serial Protocol Analyzer.
To compare monitoring sessions, follow these steps:
The ability to reproduce data transmitted between serial applications or devices and serial interfaces can provide critical information when troubleshooting communication problems. Using this serial port analyzing tool, you can send the same data stream repeatedly to monitor how an app or device reacts to the transmission.
Follow these steps to analyze data from a serial port:
SerialMonitor.exe /New COM1 11111
1rst “1” stands for the Table view
2nd “1” – Line view
3rd “1” – Data view
4th “1” – Terminal view
5th “1” – Auto start
It is a complicated undertaking to monitor the flow of data between a computer and its serial interfaces. Without using RS232 monitoring software it is extremely difficult. Individuals working with serial devices and applications can use the software to make their jobs easier in numerous ways. Professional tools such as Serial Port Monitor allow you to easily track serial traffic. The application makes it easy to log, display, monitor, and analyze all of your system’s serial data activity.
