Free Serial Analyzer OverviewFree Serial Analyzer is a non-intrusive Serial Port sniffer and software RS-232/RS-422/RS-485 protocol analyzer for Windows. Show It supports monitoring of serial port data on both 32-bit / 64-bit Windows desktop/server platforms including Windows 10. Windows 11 and Windows Server 2022 are also supported. Our software-based free serial port monitor is an ideal alternative to expensive hardware RS232/RS485/RS422 logic analyzers. This COM port analyzer utility requires no additional cabling and allows you to effectively capture/display any data and commands transmitted through your computer's serial ports. The captured raw data is automatically decoded, analyzed and each serial communication packet is then presented in an easily readable format, allowing you to quickly and efficiently analyze data exchanged over RS 232, RS 422, or RS 485 serial interfaces. For the best user experience, our product supports advanced data filtering. All intercepted serial data can be filtered by Requests, I/O Codes and even by custom filtering rules. You can consider this serial port packet sniffer an effective tool to simplify development, testing and debugging of serial applications and devices. Using our free serial protocol analyzer you don’t have to worry about any additional hardware, null-modem cables, DB-25 or DE-9 connectors and so on. It’s a pure software-based serial port sniffing solution. Just download, install and start using it in seconds! How Free Serial Analyzer WorksProgram installs filter driver on top of a serial device driver. Filter driver then intercepts I/O requests issued by an application communicating with a serial device. All control requests (requests that configure port parameters) and data transfer requests (requests that pass data between app and RS-232/RS-422/RS-485 hardware device) are monitored. Each serial data request is then parsed and displayed in an easy-to-understand form using several different views. This freeware serial snooper even allows you to trace serial data transferred between applications and devices connected to the remote PC (Device Monitoring Studio Server, network or Internet connection to the remote computer is required then).
