VT100

The VT100 is a video terminal made by Digital Equipment Corporation (DEC) which became the de facto standard used by terminal emulators. It was introduced in August 1978, following its predecessor, the VT52, and communicated with its host system over serial lines using the ASCII character set and control sequences (aka escape sequences) standardized by ANSI. In 1983, the VT100 was replaced by the more powerful VT200 series terminals such as the VT220.
