INT 21 - LANtastic - GET DOS SERVICE VECTOR

	AX = 5FE0h
Return: CF clear if successful
	    ES:BX -> current FAR service routine
	CF set on error
	    AX = error code
Note:	the service routine is called by the LANtastic redirector whenever DOS
	  may safely be called, permitting external TSRs and drivers to hook
	  into LANtastic's DOS busy flag checking
