-- Starts normal mode (default)
Bold_Mode : constant String := Latin_1.Esc & "[1m";
-- Starts bold mode
Underline_Mode : constant String := Latin_1.Esc & "[4m";
-- Starts underline mode
Blinking_Mode : constant String := Latin_1.Esc & "[5m";
-- Starts blinking mode
Reverse_Video : constant String := Latin_1.Esc & "[7m";
-- Starts reverse video mode
