--------D-214400-----------------------------
INT 21 - DOS 2+ - IOCTL - GET DEVICE INFORMATION
	AX = 4400h
	BX = handle
Return: CF clear if successful
	    DX = device information word (see #01423)
	    AX destroyed
	CF set on error
	    AX = error code (01h,05h,06h) (see #01680 at AH=59h/BX=0000h)
Notes:	value in DH corresponds to high byte of device driver's attribute word
	  if handle refers to a character device
	Novell NetWare reportedly does not return a drive number in bits 5-0
	  for a disk file
	this function was not supported by Digital Research's DOS Plus
