tio [options] device

tio is a simple serial device terminal emulator designed as a modern, user-friendly alternative to minicom and screen for serial communication. It connects to serial ports with sensible defaults (115200 baud, 8N1) and supports automatic reconnection when a device is plugged in or becomes available.
The tool provides essential serial communication features including configurable baud rates, data bits, stop bits, parity settings, local echo, session logging, and timestamps. The prefix key Ctrl+t provides access to in-session commands, with Ctrl+t q to quit.
