Versions:
SerialTool is a professional cross-platform serial port utility published by SerialTool, currently at version 3.3.0, which is the only version presently listed in this catalog entry. The software falls into the serial communication and debugging tools category, serving developers and engineers who work with serial interfaces. Its core purpose is to enable communication with, monitoring of, and debugging of serial port traffic, covering the RS232, RS485, and UART standards. Because it is cross-platform, SerialTool runs on Windows, macOS, and Linux, making it suitable for mixed-environment workflows where the same tool is needed across different operating systems. Typical use cases include exchanging data with devices connected over a serial port, observing and analyzing serial traffic during development or troubleshooting sessions, and diagnosing communication problems between a computer and serial-based hardware. To support these tasks, SerialTool includes a set of notable features: Python scripting, which allows users to script interactions with serial ports; Modbus support, relevant for work with equipment and systems that use the Modbus protocol; and a built-in Hex editor, useful for inspecting and working with data at the hexadecimal level when dealing with binary serial traffic. The utility is positioned for professional use by developers and engineers rather than casual users, and its description emphasizes its role as an all-in-one tool for serial port work rather than a single-purpose terminal. Since only one version is recorded for this product, version 3.3.0 represents both the latest and the sole documented release in the available data. Overall, SerialTool combines serial communication, monitoring, and debugging capabilities with scripting, protocol support, and low-level data inspection in a single cross-platform application for Windows, macOS, and Linux systems.
