Docklight is a Windows‑based serial communication and protocol analysis tool that has been popular among engineers, developers, and hobbyists for more than a decade. The software provides a graphical interface for sending and receiving data over RS‑232/RS‑485, USB, TCP/IP, and many other interfaces, making it a convenient alternative to command‑line utilities such as PuTTY or Tera Term.
Version 2.4, released in 2012, represented a mature point in the product’s evolution. It introduced several UI refinements, expanded script capabilities, and improved support for custom protocols. Because the product is commercial software, a valid license key is required to unlock the full feature set beyond the trial period. Docklight 2.4 License Key

| Feature | Why It Matters | |---------|----------------| | Graphical Terminal | Allows users to view, edit, and send raw byte streams without writing code. | | Script Engine (VBScript/JScript) | Automates repetitive communication tasks, performs data validation, and simulates devices. | | Protocol Definition | Users can create custom protocol “templates” that highlight fields, calculate checksums, and generate human‑readable reports. | | Logging & Export | Captured traffic can be saved as text, CSV, or binary files for later analysis. | | Multiple Simultaneous Sessions | Supports testing of master‑slave configurations on the same machine. | | Built‑in Test Suites | Pre‑configured examples (e.g., Modbus, CAN, NMEA) help new users get started quickly. |
These capabilities make Docklight a go‑to tool for tasks ranging from debugging embedded firmware to verifying industrial control communications.
The process is deliberately straightforward: a few clicks, an internet connection (or manual file import), and the full feature set becomes available.
