Introduction for Serial Port Monitor

Serial Port Monitor is a professional application for RS232/422/485 COM ports monitoring.

Serial Port Monitor monitors, displays, logs and analyzes all the serial port activity in a system.

It is a powerful system utility for exploring the way OS works and monitoring how applications use ports, for tracking down problems in system or application configurations and processes.

Main Features:

  • Serial Port Monitor and all of its internal drivers are digitally signed
  • All COM-port types are supported: standard on-board ports, extension board ports, software-based virtual COM ports, Bluetooth serial ports, USB-to-Serial cradles, etc.
  • Any software/hardware that works with a serial port can be monitored
  • Real-time data capture
  • Any number of serial ports can be monitored simultaneously
  • Monitor serial ports which are already opened by another applications (Professional/Company Edition only)
  • Easily send various types of data, apply aliases for faster typing and automation, send files and loop functions and commands, change serial port parameters on-the-fly (Professional/Company Edition only)
  • Various monitoring visualizers: table, line, dump, modbus and terminal views
  • Incoming and outgoing data streams logging
  • Intercept and record all serial input/output control codes (ioctl), tracking their full details and parameters
  • Customizable monitoring session logging (several timestamp formats, different scale of notation, customizable logging string length, etc.)
  • Convenient and flexible monitoring session’s management: saving and loading all monitored data, exporting and redirecting to file functions
  • Monitoring session exporting (HTML, ASCII text, UNICODE text, Exсel CSV) and automatic redirection to file (Serial Port Monitor will automatically append all monitored data to a file in real-time)
  • Redirected file can be either split into a bunch of files or can be limited to user-defined size
  • Export raw data to a file
  • Copying of all recorded data to clipboard
  • Full duplex mode are supported
  • Control lines status are visualized
  • Unique stream filtering tools with presets
  • All baudrates are supported
  • Flexible configuration: stopbits, flow control, parity control, data bits, highlighting, etc.
  • Precise request timing can be used to test different software
  • User-friendly flexible interface: no programming skills are required

Serial Port Monitor can be used for: 

  • monitoring serial data exchange between serial devices and any Windows application
  • debugging computer connection with peripheral devices using COM ports, such as modem, mini-ATS, projector, etc.
  • solving problems with serial (RS232/422/485) data communication control networks and devices
  • implementing, debugging and reverse-engineering serial protocol
  • sending and capturing binary, ASCII and HEX data passing via serial connections
  •  convenient interaction with any equipment over RS232/RS422/RS485 interface
  • serial devices drivers development
  • development of hardware with serial interfaces
  • hardware and software testing

Serial Port Monitor can be successfully used by: 

  • programmers and beta-testers
  • quality-control engineers
  • peripheral software developers
  • OEM development and test engineers
  • system integrators
  • field service and maintenance engineers
  • industrial control and SCADA design engineers

System Requirements:

  • Windows 2000/XP/2003/Vista/7/Server 2008/2016/x64
  • at least one COM port
