ANSI escape sequence is a sequence of ASCII characters, the first two of which |
|
10 |
are the ASCII "Escape" character 27 (1Bh) and the left-bracket character " [ " |
|
11 |
(5Bh). The character or characters following the escape and left-bracket |
|
12 |
characters specify an alphanumeric code that controls a keyboard or display |
|
13 |
function. |
