After some trial, I found that
"!0,1,0" and "!0,0,0" will generate a full-update.
"!0,1,1" and "!0,0,1" will generate a typing-update.
And no respone for "!1,1,1", "!1,1,0", "!1,0,0", "!1,0,1".
So, I am trying the following code to see if typing refresh can make some improvement to screen update.
Quote:
if(width>400||height>500){
sprintf(msg, "!0,1,0");
}else{
sprintf(msg, "!0,1,1");
}
