INT 14 - MBBIOS - READ BUFFER

	AH = 0Bh
	CX = size of buffer
	ES:DI -> buffer
Return: AH = composite line status (see #00304) formed by ORing all statuses
		  on receive interrupts; bit 0 set if additional characters
		  available
	AL = composite modem status (see #00305) formed by ORing all statuses
	CX = number of characters actually read
	DI updated
Note:	the PACCOM version of MBBIOS does not use CX or ES:DI on call,
	  instead returning ES set to the segment of the buffer containing a
	  received packet, or 0000h if no packets available; the buffer may
	  be freed with AH=0Ch"MBBIOS"
