ComTool is a cross platform serial port debugging tool that enables users to communicate with various devices through serial ports.

ComTool has a super slick interface and is designed for developers, testers and hobbyists who need to work with serial port devices such as Arduino, Raspberry Pi, GPS modules, sensors and more. It has both light and dark themes and plugin support as well. (See docs/plugins.md)

ComTool supports testing on serial, TCP UDP and SSH connections. It allows you to send and receive data from multiple serial ports simultaneously, monitor the data flow and analyze the data packets. You can also customize the display settings, save and load configurations, and export the data to various formats.

ComTool is a portable app, so, for Windows, just unzip the file to wherever you like and run the comtool.exe file to start. For other OS's it's probably best to check the authors site for the latest instructions.
