248;infomration since it also hooks INT 10h vector.
249;For this DA_SETMODE_FLAG purpose, DA_INFO_LEVEL and DA_INFO_DIRECTION should always be
250;set to 0. This can be extended for another information passing scheme between
251;DISPLAY.SYS and ANSI.SYS in the future version.
252;For DA_SETMODE_FLAG, DISPLAY.SYS should be extremely careful that when it calls
253;with DA_SETMODE_FLAG =1, then it should calls with DA_SETMODE_FLAG=0
254;when it finished INT 10h function call. Otherwise, the system goes .....
