# SerialTool - Advanced Serial Port Utility, Monitor, and Sniffer

SerialTool is a powerful and versatile software designed for serial communication across **Windows, macOS, and Linux**. It functions as a Serial Port Utility, Serial Port Monitor, and Serial Port Sniffer, making it an essential tool for both hobbyists and professionals.

SerialTool supports multiple **COM ports simultaneously**, enabling concurrent monitoring, communication, and control. It features hexadecimal and ASCII viewers, read/write consoles, and traffic logging with timestamp precision. With built-in support for **Modbus RTU and Modbus ASCII**, it includes a Modbus client for quick protocol testing.

Advanced users benefit from a built-in **Python** scripting engine for automation, serial-to-network bridging, timed packet sending, and automatic response triggers based on incoming data.

SerialTool also includes **Virtual COM Port emulation**, allowing you to create, link, and manage virtual port pairs for simulation and loopback testing.

For deeper insight, SerialTool offers a **serial sniffer** kernel driver (on Windows) that captures low-level I/O control (IOCTL) signals and raw serial data, even from ports opened by other applications. It features a live session log, byte visualizer, structured packet list, IO controls, and a SerialScope for graphical waveform analysis.

Data can be exported in binary, hex, ASCII, and directly to **.pcap files for Wireshark** analysis. A variety of UI themes and dockable windows provide a fully customizable user experience.

Whether you're developing firmware, debugging hardware interfaces, or reverse-engineering devices, SerialTool delivers the reliability, flexibility, and depth you need in a professional-grade serial communication suite.
