Configure every port detail — baud rate, parity, data/stop bits, flow control, and modem lines (DTR, RTS) — for RS-232 and RS-485 devices through any USB-to-serial converter. Make Modbus RTU readable at a glance with automatic frame detection, field interpretation, and CRC handling.
AI Assistant (BYOK) can help you use ComIO.Studio — or take over the work entirely. Connect your own supported AI provider account or local model (beta), then work through the built-in chat. It can analyze communication, troubleshoot connections, and help reverse-engineer unknown protocols.
ProBaud lets the AI agent you already use — Claude Code, Cursor, VS Code — reach your serial port. You see everything it sends in the terminal, and each tool can be allowed, set to ask, or switched off.
A serial port monitor: view ASCII, HEX, Modbus RTU, and VT100 data with search, timestamps, and connection stats. The Modbus decoder turns raw RS-485 traffic into readable requests, responses, values, and CRC status.
Lua scripts with full access to the serial port can automate virtually anything, from measurements and monitoring to communication analysis, frame generation, device control, and complete test sequences.
ProBaud unlocks measurement charts recorded by Lua scripts. Log data to disk and visualize it live or later, combine multiple quantities, create standard plots or spectral waterfalls, and export results as PNG.
Keep up to ten one-click text or hex commands always at hand. Define each command once, choose its line ending, and fire it instantly from the top bar — settings persist across restarts.
Watch incoming serial data and respond automatically when a text pattern appears. Handle logins, keep-alives, and routine device prompts with rules you can enable or disable individually.
Flash firmware straight from the terminal to ESP8266, ESP32, STM32, and AVR over UART. No external programmer or separate tool needed — just connect via USB-to-serial and flash.
Native performance on Linux, Windows, and macOS, with fast startup, a small footprint, and direct system-level access.
