183 ;DISPLAY.SYS is calling/finishing INT 10h SET MODE call. ANSI.SYS needs this
184 ;infomration since it also hooks INT 10h vector.
185 ;For this DA_SETMODE_FLAG purpose, DA_INFO_LEVEL and DA_INFO_DIRECTION should always be
186 ;set to 0. This can be extended for another information passing scheme between
187 ;DISPLAY.SYS and ANSI.SYS in the future version.
188 ;For DA_SETMODE_FLAG, DISPLAY.SYS should be extremely careful that when it calls
189 ;with DA_SETMODE_FLAG =1, then it should calls with DA_SETMODE_FLAG=0
190 ;when it finished INT 10h function call. Otherwise, the system goes .....
191 ;
192 ;D425. At the request of OS2 compatibility box, when the user ask to ANSI
