The TTY subsystem is central to the design of Linux, and UNIX in general. The TTY system in Linux is a throwback to when computers first because interactive in real-time,but is still very much relevant today. Unfortunately, its importance is often overlooked, and it is difficult to find good introductory articles about it. The TTY demystified is a fantastic essay on the subject.
