What is ComIO.Studio?

A professional serial terminal with built-in AI — for engineers who talk to hardware.

1. Overview — What ComIO.Studio Does

ComIO.Studio is a cross-platform desktop application that serves as an all-in-one workstation for anyone who communicates with hardware over serial ports (UART, RS-232, USB-to-serial).

In one application, you get:

• Serial Terminal — connect to any serial device, send/receive data in text or hex, monitor control lines (RTS, DTR, CTS, DSR, DCD, RI)
• Data Buffer & Logging — searchable scrollback with timestamps, ASCII/HEX modes, export to file
• MCU Programmer — flash firmware to ESP8266, ESP32, STM32, and AVR chips directly through the serial port (UART) — no external programmers needed
• Macros (M1–M6) — one-click command shortcuts for frequently used commands
• Triggers — automatic responses when specific text patterns are detected in incoming data
• Lua Scripting — full automation engine with serial port API access
• AI Assistant — ask questions about your serial data, get protocol decoding, generate code, troubleshoot connections

ComIO.Studio runs natively on Linux, Windows, and macOS. Small binary size (~30 MB), instant startup, and direct hardware access — no bloat.

2. Who Is It For?

3. What Makes ComIO.Studio Different?

Traditional serial terminals are just terminals — they let you send and receive text, and that's it. ComIO.Studio goes far beyond that:

4. Features In Detail

Serial Communication

Connect to any serial port with full configuration:

• Baud rate: wide range of presets from 300 to 4,000,000
• Data bits: 5, 6, 7, 8
• Parity: None, Odd, Even
• Stop bits: 1, 2
• Flow control: None, RTS/CTS (hardware), XON/XOFF (software)
• Control lines: Toggle RTS and DTR manually; read-only indicators for DSR, CTS, DCD, RI

USB hotplug detection — ports appear/disappear automatically when you plug/unplug USB devices. No need to refresh.

Data Buffer & Logging

• Configurable buffer size (5–20 MB of scrollback)
• ASCII, HEX, and combined ASCII+HEX display modes (switch on the fly)
• Toggleable timestamps for RX and TX separately
• ANSI color code support and VT100 terminal emulation
• Full-text search with match navigation
• Save terminal contents to file
• Separate logging module with Text/Hex/Mixed format and downloadable log files
• RX/TX byte counters, connection uptime, reconnection tracking

MCU Programmer

Flash firmware directly from ComIO.Studio to your microcontroller through the serial port (UART bootloader) — no external hardware programmers (JTAG/SWD) are needed, just a USB-to-serial connection:

• ESP8266 / ESP32 — built-in serial flasher, auto-detect chip, configure flash size/mode/speed
• STM32 — UART bootloader flashing
• AVR — serial bootloader (STK500) flashing

Multi-segment flashing, progress indicator, chip detection, configurable flash parameters.

Macros (M1–M6)

Six quick-access macro buttons, each configurable with:

• Custom label and command text
• Line ending: CR, LF, CRLF, or None
• Text or HEX format
• One click = instant send

Triggers

Automatic rules that watch incoming data and respond:

• Pattern: text pattern to match in received data
• Response: automatically send a configured reply (text or hex, with chosen line ending)
• Enable/disable individual triggers or all triggers at once
• Example: When device sends Password:, automatically respond with mypassword\r\n

Lua Scripting Engine

Full Lua 5.4 scripting environment with serial port API. Automate anything:

• Send/receive data programmatically
• Parse complex protocols
• Create automated test sequences
• Build custom tools and converters

AI Assistant

Built-in chat with an AI that has context about your serial connection:

• Sees your port configuration (baud, parity, etc.)
• Sees recent terminal output (what your device is sending)
• Can analyze protocols, decode hex, generate Lua scripts, troubleshoot connections
