; initialize the byte as 8 bit variable.

MISC_FLAGS EQU	<B>41h</B> ; BIT ADDRESSABLE.
		   ; BIT 0: KB ENABLED; SET AT FE ACK
	           ; BIT 1: INTERNAL BEEP SUPPRESSED
		   ; BIT 2: RE-START
		   ; BIT 3: THE FIRST "FD" OF THE PACKET HAS  COME FROM MAIN PROCESSOR
		   ; BIT 4: IF SET FUNCTION IS RECEIVED FOR PACKETIZED MODE 
		   ; BIT 5: IF SET FIRST "FD" HAS BEEN TRANSMITTED	FROM Q2		
		   ; BIT 6: IF SET ADDRESS IS RECEIVED FOR PACKETIZED MODE	
		   ; BIT 7: PACKETIZED MODE

later in my code I could use this byte as a bit. 

TX_QUEUE1:JB  MISC_FLAGS.7,TX_QPACKET ; JIF 'PACKET CODE' RECEIVED
PUT_C1:	JB MISC_FLAGS.5,TX_QPACKET  ;JIF IN THE MIDDLE OF SENDING Q2 PACKETS  

TX_QPACKET: ret
