Overview
The Advanced Video Attribute Terminal Assembler and Recreator (AVATAR) protocol is a system of escape sequence
Escape sequence
An escape sequence is a series of characters used to change the state of computers and their attached peripheral devices. These are also known as control sequences, reflecting their use in device control. Some control sequences are special characters that always have the same meaning...

ANSI escape sequences are characters embedded in the text used to control formatting, color, and other output options on video text terminals. Almost all terminal emulators designed to show text output from a remote computer, and to show text output from local software, interpret at least some of...

Avatar was later extended in late 1989 to AVT/0 (sometimes referred to as AVT/0+) which included facilities to scroll areas of the screen (useful for split screen chat, or full screen mail writing programs), as well as more advanced pattern compression.

Avatar was originally implemented in the Opus BBS, but later popularised by RemoteAccess
