.. contents:: :local:
+TTY line discipline process all incoming and outgoing character from/to a tty
+device. The default line discipline is :doc:`N_TTY <n_tty>`. It is also a
+fallback if establishing any other discipline for a tty fails. If even N_TTY
+fails, N_NULL takes over. That never fails, but also does not process any
+characters -- it throws them away.
