The Xterm terminal emulator. In the early 1980s, large amounts of software directly used these sequences to update screen displays. This included everything on VMS (which assumed DEC terminals), most software designed to be portable on CP/M home computers, and even lots of Unix software as it was easier to use than the termcap libraries, such as the shell script examples below in this article.

In most cases these developed as true extensions of ASCII, leaving the original ...

A block-oriented terminal may be card-oriented, display-oriented, keyboard-display, keyboard-printer, printer or ...
