title: Set priority to events
body: <p>I am making an application in QT. I use QExtSerialPort to receive data from the serial port of my comp (whenever the readyread() signal is emitted). I also have some timers running doing other stuff at certain intervals. Now I noticed that when the timers are turned on, not all the data of the readyread signal is emitted a lot less, then when the timers are not turned on. Is there a way in QT to make sure that all the data of the serial port is received? Maybe by setting a high priority to the readyread event or something like that?</p>
