21.8.2. Using screen to Connect to the Serial Console

The screen tool serves as a capable serial terminal. To install it, run as root:
~]# dnf install screen
To connect to your machine using the serial console, use a command in the follow format:
screen /dev/console_port baud_rate
By default, if no option is specified, screen uses the standard 9600 baud rate. To set a higher baud rate, enter:
~]$ screen /dev/console_port 115200
Where console_port is ttyS0, or ttyUSB0, and so on.
To end the session in screen, press Ctrl+a, type :quit and press Enter.
See the screen(1) manual page for additional options and detailed information.
