This  example  reads  and displays the contents of the
keyboard  typeahead  buffer which is used, by ROM-BIOS
to  store  keystrokes  before they are processed.  The
Assembly-language  Toolbox  contains several functions
which  can  be used to control the keyboard, including
one  which  will flush the typeahead buffer of pending
keystrokes, clearing the way for fresh input.
