Notes:	hooked by TI MS-DOS, which provides a PRTSCRN character device which
	  can invoke screen prints when a decimal digit (indicating the type
	  of screen dump) is written to it
	the TI MS-DOS print-screen routine allows selective dumps of text
	  only, graphics only, or text and graphics superimposed, in either
	  normal or reverse, by pressing the appropriate keystroke combination:
	  Shift-Print, Ctrl-Print, Alt-Print, Shift-Alt-Print, Ctrl-Alt-Print,
	  or Shift-Ctrl-Print.
	the BIOS default routine for this vector is an IRET
