The TTY demystified. Learn you an arcane computing history, terminals, shells, UNIX, and even more arcanery! Terminal emulators are about the most reliable, versatile tools in my not-so-modern computing toolkit. It’s nice to know a little more about how they work, besides “lots of magic ending in -TY”, e.g. teletypes, pseudo-terminals, session groups, etc.
