;Info Struture for DA_INFO_2F. (DS:DX point to this packet)
;J.K. Note: For DOS 4.00, DA_INFO_PACKET is used by DISPLAY.SYS to signal ANSI.SYS that
;DISPLAY.SYS is calling/finishing INT 10h SET MODE call.	ANSI.SYS needs this
;infomration since it also hooks INT 10h vector.
;For this DA_SETMODE_FLAG purpose, DA_INFO_LEVEL and DA_INFO_DIRECTION should always be
;set to 0.	This can be extended for another information passing scheme between
;DISPLAY.SYS and ANSI.SYS in the future version.
;For DA_SETMODE_FLAG, DISPLAY.SYS should be extremely careful that when it calls
;with DA_SETMODE_FLAG =1, then it should calls with DA_SETMODE_FLAG=0
;when it finished INT 10h function call. Otherwise, the system goes .....

;D425. At the request of OS2 compatibility box, when the user ask to ANSI
; with DA_INFO_LEVEL=1, then ANSI sets DA_OPTION_L_STATE based on /L option
; status.
