The terminal interprets these sequences as commands, rather than text to display verbatim.ĪNSI sequences were introduced in the 1970s to replace vendor-specific sequences and became widespread in the computer equipment market by the early 1980s.
Certain sequences of bytes, most starting with an ASCII escape character and a bracket character, are embedded into text. ANSI escape sequences are a standard for in-band signaling to control cursor location, color, font styling, and other options on video text terminals and terminal emulators.
