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.
