A terminal is a standalone screen and keyboard without the rest of the computer, connected to a serial bus using a network connector. It reads and writes serial data verbatim. Use a serial card in a computer to enable interaction with the computer.

The console can be moved to a terminal:

The shell then runs on the terminal, and the computer's own screen stays unchanged. It can be moved back using console /dev/ttyS0. To do this automatically at boot time, in /init.d/50-console.lua:

The default on both ends is 9600 baud. For faster output, set the same rate in the terminal's settings and with stty -F /dev/ttyS1 115200.

Use getty to spawn a session on the terminal:

Switch to an external terminal like so:

Configure the terminal address and baud rate in its settings screen. To access this screen, either open the terminal with a wrench, or switch to the settings screen using the toggle button on the left of the terminal screen.
