int VGA_Term_Print(char *string);
int VGA_Color(int col);
Clear the screen then print “Chameleon”.
Print the character ‘X’ in all colors.
functionality should be maintained for any drivers that you develop, so users can have a standard set of
base “terminal” functionality. You can send the following ASCII codes (some functions are redundant):
$00 = clear the screen.
$01 = home the cursor to top left.
$08 = backspace.
$09 = tab (8 spaces per).
$0A = set X position (X follows).
$0B = set Y position (Y follows).
$0C = set color (color follows).
$0D = return (carriage return and linefeed).
Description:
scrolling, etc. if the string prints off the right of the screen or bottom of terminal. Returns 1.
Description:
col parameter should be from [0..7] and selects one of a number of different foreground background color
schemes for the characters printed. Returns 1.
VGA_Term_Print(…) prints a NULL terminated string to the screen with automatic
VGA_Color(…) sets the color of the text and background (depending on driver). The
