INT 14 - X00 FOSSIL - EXTENDED SERIAL PORT STATUS/CONTROL

	AH = 1Fh
	DX = port number
	AL = direction
	    00h read modem control register
		Return: BL = modem control register (see #00349)
			AH = status
	    01h write modem control register
		BL = modem control register (see #00349)
		Return: AX = status
Notes:	this function is intended to exactly emulate the PS/2 BIOS AH=05h call
