Is there a cross platform way to receive a signal (or other notification) in Qt, when a new serial port device becomes present, or one that was present before becomes absent? This is a simple case of getting to know when someone connected a new USB to serial port converter (discovering COM ports in windows and ttyS in linux). My only idea now is to periodically (for example using QTimer) run the QSerialPortInfo routines. Is there a way to accomplish this with event driven system? I would appreciate all help.
