A very extensive Modbus client available in pretty much any terminal.
Made in pure safe Rust, based on tokio-modbus and ratatui (with ratzilla for the web demo).

• Modbus TCP and RTU, plus a built-in mock device for playing around
• Live register reading with auto-refresh, pause/resume and slave id selection
• Interpretation columns with configurable word order: u16, i16, hex, binary, ASCII, u32, i32, f32, f64, M10K (and more!)
• Panels: main view, pinned, labeled, custom rules and an address matrix
• Pin, label and custom-rule registers; jump to address or label
• Value graph for a register over time
• Register writes, with a write log and an optional read-only mode
• HTTP API (POST /read, POST /write)
• Dump read data to a file, copy addresses to the clipboard
• Configurable via config.json (or --config <path>) and an in-app settings screen

Press h inside the app for all available keybinds.
