Notes: For a keyboard in keystroke mode, the input buffer is a single byte containing the character code as returned by the BIOS; the BIOS scan code is available via the STATUS call if the character is zero. For a keyboard in field mode, the input buffer format is determined by the field table header for the window the keyboard is attached to. Keyboard input buffers and mailbox message buffers may be invalidated by the next READ, ERASE, CLOSE, or FREE message to the same object
