It may capture serial port traffic which flows via Com ports created by our Free Virtual Serial Ports.It monitors data from plug and play (PnP) serial ports and I/O ports (COM Ports) interfaced by 16550 UART: COM1, COM2, COM3, COM4 … COMn custom and virtual serial ports registered and visible in Windows device manager under standard Ports (COM & LPT) device class.It displays the status of Serial (Modem) control lines: Transmitted Data TxD, Received Data RxD, Data Terminal Ready DTR, Carrier Detect DCD, Data Set Ready DSR, Ring Indicator RI, Request To Send RTS, Clear To Send CTS.It intercepts and traces all Input/Output Control Code Requests (IOCTLs) and I/O Request Packets (IRPs) from DTE (data terminal equipment) and DCE (data circuit-terminating equipment) devices.Our Freeware Serial Port Monitor allows you to capture and decode monitored packets in real time even at high and non-standard data transfer rates. Our Free Serial Port Snooper supports all modern Windows server and desktop platforms starting from Windows Vista, including Windows 11 and Windows 10 operating systems. 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).ĭownload this free com port monitoring software now! Free Serial Analyzer OS support: Each serial data request is then parsed and displayed in an easy-to-understand form using several different views. 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.

Just download, install and start using it in seconds! How Free Serial Analyzer Works It’s a pure software-based serial port sniffing solution. 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. You can consider this serial port packet sniffer an effective tool to simplify development, testing and debugging of serial applications and devices. All intercepted serial data can be filtered by Requests, I/O Codes and even by custom filtering rules. 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.įor the best user experience, our product supports advanced data filtering. 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. Our software-based free serial port monitor is an ideal alternative to expensive hardware RS232/RS485/RS422 logic analyzers. Windows 11 and Windows Server 2022 are also supported. It supports monitoring of serial port data on both 32-bit / 64-bit Windows desktop/server platforms including Windows 10. Free Serial Analyzer is a non-intrusive Serial Port sniffer and software RS-232/RS-422/RS-485 protocol analyzer for Windows.
