/*! \class QextSerialEnumerator
\brief The QextSerialEnumerator class provides list of ports available in the system.
\section1 Usage
To poll the system for a list of connected devices, simply use getPorts(). Each
QextPortInfo structure will populated with information about the corresponding device.
\bold Example
\code
QList<QextPortInfo> ports = QextSerialEnumerator::getPorts();
foreach (QextPortInfo port, ports) {
// inspect port...
}
\endcode
To enable event-driven notification of device connection events, first call
setUpNotifications() and then connect to the deviceDiscovered() and deviceRemoved()
signals. Event-driven behavior is currently available only on Windows and OS X.
\bold Example
\code
QextSerialEnumerator *enumerator = new QextSerialEnumerator();
connect(enumerator, SIGNAL(deviceDiscovered(const QextPortInfo &)),
myClass, SLOT(onDeviceDiscovered(const QextPortInfo &)));
connect(enumerator, SIGNAL(deviceRemoved(const QextPortInfo &)),
myClass, SLOT(onDeviceRemoved(const QextPortInfo &)));
\endcode
\section1 Credits
Windows implementation is based on Zach Gorman's work from
\l {http://www.codeproject.com}{The Code Project} (\l http://www.codeproject.com/system/setupdi.asp).
OS X implementation, see \l http://developer.apple.com/documentation/DeviceDrivers/Conceptual/AccessingHardware/AH_Finding_Devices/chapter_4_section_2.html
