Analyze serial port data with the best software

Olga Weis

RS232 standard is popular in many scientific directions and is widely used for lab equipment, quality and process controllers, various sensors, measuring tools, etc. However you may experience some issues while trying to analyze serial port activity. A number of aspects has to be taken into consideration: hardware and cabling, communication settings and protocols. To be able to perform COM monitor activities successfully and detect any issues with serial data, you'll need a reliable serial port sniffer with a comprehensive RS232 activity log.

Serial Port Monitor
  • With RS232 Analyzer you can connect to ports that are already open and start monitoring at once. Data is captured in real time and displayed conveniently. Data packets are easy to compare. You can record IOCTLs with all details and parameters.

  • This COM port sniffer can monitor several ports at once so users can get the data on how apps interact with several serial devices within a session. The collected data can be viewed as table, line, dump or terminal, with sump view being able to show binary, ASCII data and port settings. Another great feature this serial port testing software offers is emulating data transmission to a serial device so you can see and analyze the reaction of a device to certain commands and data. You can send string, binary, octal, decimal, hexadecimal, or mixed data.

  • The popular Modbus RTU and Modbus ASCII protocols are fully supported with all essential filters for the most effective analysis.

  • Serial Port Analyzer is the most precise RS232 testing software thanks to the possibility to reproduce the monitoring session in order to review certain port behavior with the same parameters used in different conditions.

  • The software comes with comprehensive help system and intuitive interface, which makes it fairly simple to use.

HDD Software


Another software solution, without any hardware needed. Free Serial Port Monitor can intercept, display and analyze data exchange between a device and a serial application. Also a useful solution for software, device driver or serial hardware development that helps you test, debug, and optimize your product. It will dig into data flows and protocols and display everything in a comprehensive way.

With this program, you’ll be able to capture data and serial input/output control codes (IOCTLs) going through a COM port.

Free Serial Protocol Analyzer provides users working with COM ports with a full set of information — the app allows formatting data into different kinds of output. What’s more, it offers emulation of data sending on behalf of a monitored app. This option will clearly help you better check the reaction of a COM port to some particular data.

What is also convenient is that the software allows searching for a text in a Data View, Request View, and Console View. Plus, it’s possible to change the way the hex data displayed in Request View and Data View.
