microcom

Open a serial port using the specified baud rate

$ microcom -p [/dev/ttyXYZ] -s [baud_rate]

$ microcom -t [hostname]:[port]

microcom [options]

microcom is a minimalistic terminal program for accessing remote devices via serial ports, CAN bus, or telnet connections from the console. It provides a simple, lightweight alternative to programs like minicom for basic serial communication needs.
The program passes data between the terminal and the remote device, useful for accessing embedded systems, routers, network equipment, and other devices with serial console interfaces.
Exit microcom by pressing Ctrl+\\ followed by q (or the configured escape sequence).

-p, --port _device_

Serial port device to connect to (e.g., /dev/ttyUSB0)

Baud rate for serial communication (e.g., 9600, 115200)

Connect via telnet to the specified host and port

Connect to a CAN bus interface

Log session to a file

Serial port access typically requires appropriate permissions (membership in the dialout group on most Linux systems). The device must be configured for the correct baud rate, parity, and stop bits to match the remote device. No built-in file transfer protocols like XMODEM or ZMODEM.
