Thanks @thiton. Can you please elaborate on your example of ssh? How does it use pty/tty? How does master/slave role play in ssh?

ssh allocates a pty for the shell it creates. The shell is connected to the slave end and thereby can rely on all the capabilities of a normal terminal (e.g. termcap if I remember correctly), and the ssh daemon connects to the master end and sends and receives its input there.
