;R04	03/17/98 RCH	Changed default POST output I/O port from 300H to 80H
;			According to this change, we don't need to define	
;			switch "SPECIAL_DEBUG_PORT" & "DEBUG_PORT" in bios.cfg
;			if the I/O port 80H is used
;R03 	06/06/97 PTY	Add code for RPB
;R02	07/11/96 RAX	Add Two_debug_PORT define for special case need out
;			post code to 80h & other
;R01	OCT-15-90 SMS	adding copyright stmt.
;R00	06/01/90 TIM    Initial release for 4.0

;
; All macros in this file are in alphabetical order...

;[]==============================================================[]
;
;POST_CODE:
;
;	Sends a value out to the debug port (usually port 80h).
;	This value can come from a register or be an immediate 
;	value.
;
;SAVES: All
;
;EXAMPLES:
;
;		POST_CODE 40h
;
;		POST_CODE bl
;
;NOTES:	1.	The equate POST_STACK is used to determine whether
;		or not there is any stack when the macro is used.
;		If POST_STACK is not defined, AL will be destroyed.
;		If POST_STACK is defined, AL will be saved.
;	2.	This macro will work correctly with byte and word
;		registers (except SP)
