Newer versions of atcore can return connected devices using the QSerialPort info for places where we can't deploy solid
Clients have two ways to get this list you can call AtCore::serialPorts() to get a QStingList of the connected serial devices.
You can also use the signal AtCore::portsChanged to get this list at a timed interval. In order to enable this you must first set the serial timer interval to a non 0 value using AtCore::setSerialTimerInterval.
