Qt-ish external libraries: getting serial port and pcap functionality into Qt applications

But even with such an array of modules, from time to time a Qt developer may face some issues dealing with specific domains not cover by the Qt framework. Fortunately, some work have been done outside the framework itself that allow us to get support for serial port accces and the Pcap library.
