INT 2C - Cloaking - SET PORT-TRAPPING PASSALONG

	AX = 002Dh
	DX:EBX = new I/O trapping passalong address (see #02566)
Return: CF clear
Notes:	RM386 calls the passalong address whenever an access to a monitored
	  I/O port is attempted; the handler should check whether it is a port
	  that it is interested in, and if not call the previous passalong
	  address (which was retrieved with AX=002Ch before installing the
	  new handler)
	this function was first introduced with RM386 (RAM-MAN/386) v6.00
