What’s new in version 2.1.5

Major Improvements
  • ByteVisualizer - Visualize Bytes and Bits Graphically.
  • Added the ByteVisualizer, which allows you to display one or more bytes as bits in a graphical format. Bytes and their corresponding bits can be viewed in their standard format as well as in Serial Protocol format, enabling users to observe how data is actually sent/received via the serial port. This feature is highly useful for educational purposes, offering numerous options and customization possibilities. Some features of this SerialTool module are reserved for PRO users.
  • Multiple Buffer with Named Saves - Save Multiple Buffers with Custom Names
  • Added the ability to assign and save multiple buffers with specific names for each, making it quicker and easier to reference them when needed.
  • Serial Configuration on the Fly - Change Serial Settings Without Close/Open of the Serial Port
  • Implemented the ability to change the settings of various serial ports "on the fly" without needing to close and reopen the serial port.
  • Hex Edit and Real-Time Validation - Real-Time Hex Buffer Validation and Auto-Correction
  • Added real-time validation of the buffer length when sending data to the serial port. Also introduced automatic correction of spaces when performing copy-paste operations in the dedicated buffer edit box.
  • HexView Editor Preset Saving - Save Color Presets in HexView Editor
  • Added the ability to save color presets for specific bytes of interest in the HexView editor when this feature is enabled.
Minor Improvements
  • Improved Combo Box Appearance
  • Adjusted the graphical appearance of Combo Boxes for SerialTool's official Dark and Light styles.
  • General GUI Improvements
  • Minor General GUI Enhancements
  • Made minor general improvements to the graphical user interface.
Bug Fixes
  • Custom Baudrate Support - Fixed Custom Baudrate Support for Linux and macOS
  • Fixed the configuration of custom baud rates on Linux and macOS. It is recommended to ensure that the USB-Serial converter and the operating system support custom baud rates.
  • Application Position Adjustment - Application Position Restored After Monitor Disconnection
  • Fixed the issue where the application would start outside the screen if the secondary monitor was disconnected since the last session.
  • Now, the application is correctly repositioned to the center of the primary screen.

That's a great software for serial port. One of the few existing for MAC and it is great to have it. It is super easy to use it.

Well frankly speaking I was doubtful when I first saw all supported features. So far this software looks great especially if you are looking for a serial port software when you are developing on embedded systems. I would suggest you this if you are using an Arduino board. The User Interface is straight forward even if I personally like keyboard shortcuts. Great job guys...
