Commy is a cross-platform serial monitor for communicating with tty, UART, and COM port devices.
It runs on Linux, macOS, and Windows, and is designed as a small console utility for working directly with serial connections. The project also incorporates a VT220/xterm/ECMA-48 terminal emulator so terminal behaviour is more consistent across different host terminals.
This is free and open source software.
Key Features
- Lists available serial ports from the command line.
- Connects to serial devices using a specified baud rate.
- Supports logging received device output to a file.
- Offers optional local echo for devices that do not echo typed characters.
- Provides configurable parity, word size, stop bits, and flow control.
- Includes scrollback history that replays terminal screen updates visually.
- Ships as a single statically linked binary with no additional runtime files required.
