Set Graphic Rendition command              ESC[#;...;#m

   Sets screen foreground and background colors, controls Blink, high
   intensity, etc.  This is the one to use to set different foreground/
   background colors.  I will give several examples here.

              Example:  ESC[0m

              This will set the screen to black and white.  Every
              character entered after this command will have black
              background and white foreground in normal intensity,
              non blinking.  It turns off the Blink, High intensity
              and colors.


              Example:  ESC[34;41m

              This will set colors to Blue foreground/Red background.
              Every character entered after this command will be Blue
              on a Red background.

              Example:  ESC[1;33;42m

              This will set a foreground color of HIGH INTENSITY Yellow
              and a background color of Green.  * NOTE - Background
              colors are always normal intensity! *


              Example:  ESC[5;35;40m

              This will set BLINKING foreground color of Magenta and a
              Black background.
