High-performance serial debug assistant — Rust + Tauri
English · 中文
After many years of embedded/microcontroller work, I had tried every serial tool out there — but none felt right except sscom (a classic Chinese serial tool). So I never switched.
But sscom has pain points that were never fixed:
- Auto-scroll can't pause — data keeps pushing the view down; look back and it snaps to bottom
- Multi-string panel steals screen space — embedded in the main window, takes half the UI
- UTF-8 encoding broken — Chinese text garbled without manual byte calculation
- No dark theme — blinding white interface in a dim lab
- Can't pin window — constant alt-tab while reading PDF datasheets
- No receiver search/filter — hunting for a specific packet means squinting at a wall of text
With the help of AI-assisted coding, I decided to build a modern replacement. Issues and PRs welcome.
- 🔥 MCP (Model Context Protocol) Server — built-in MCP HTTP server lets AI agents (opencode, Claude Desktop, etc.) read serial data, inspect port status, and send commands in real time. Enable in settings, connect at
http://localhost:9876/mcp. - 🔥 Repeat line folding — auto-fold identical consecutive lines into
[×N], click to expand, right-click for copy / fold below - ⭐ Serial communication — auto-enumerate COM ports with device descriptions, hot-plug support
- ⭐ Dual-mode I/O — text / Hex send and receive, switch on the fly
- ⭐ Receive filter — keyword / regex filter, case-sensitivity toggle, Ctrl+F to focus
- ⭐ Multi-string sender — independent window, drag-to-reorder, per-item Hex/delay, loop mode, JSON import/export
- ⭐ Auto-scroll — pauses on manual scroll, resumes at bottom
- ⭐ Timestamps — bidirectional send/receive timestamps
- ⭐ Pin window — main window and multi-string window both support always-on-top
- ⭐ Themes — dark / light / system / high-contrast
- ⭐ Encoding — UTF-8 / GBK selectable, solves Chinese garbled text
- ⭐ Checksum — CRC16-Modbus / CRC32 / ADD8 / XOR8, custom insert position
- ⭐ File upload — chunked send with abort support
- ⭐ Save received data — dump receive buffer to file
- ⭐ UI customization — font family, size, and color picker
- ⭐ Persistent config — all settings auto-saved
Main window — dark theme, filter bar, multi-string panel
Multi-string sender — drag-to-reorder, per-item Hex/delay, loop mode
Repeat line folding — auto-fold identical consecutive lines into [×N], click to expand, right-click for copy / fold below
