Business Glossary

the use of ANSI standard sequences of characters (escape sequences) that, when sent to the screen of a computer, make it perform actions such as clearing the screen. These codes are used onVT-100-compatible terminals andTelnet programs (see VT-100 ).

All ANSI control sequences begin with Esc (code 27) followed by a left square bracket; many of them contain numbers that specify how far the cursor is to be moved or where it is to be placed. For example, Esc[ 2 Jclears the screen, Esc[ 1 5 C moves the cursor 15 spaces to the right, and Esc[ 3 Cmoves it only 3 spaces to the right.
