INT 29 - DOS 2+ - FAST CONSOLE OUTPUT

	AL = character to display
Return: nothing
	BX may be destroyed by some versions of DOS 3.3
Notes:	automatically called when writing to a device with bit 4 of its device
	  driver header set (see also INT 21/AH=52h)
	COMMAND.COM v3.2 and v3.3 compare the INT 29 vector against the INT 20
	  vector and assume that ANSI.SYS is installed if the segment is larger
	the default handler under DOS 2.x and 3.x simply calls INT 10/AH=0Eh
	the default handler under DESQview 2.2 understands the <Esc>[2J
	  screen-clearing sequence, calls INT 10/AH=0Eh for all others
