+Location of qextserialport project is here:
+
+http://code.google.com/p/qextserialport/
+
+
+
+However there is an alternative in qserialdevice:
+
+http://qt-apps.org/content/show.php/QSerialDevice?content=112039
+
+This appears better but much newer.
+
+
+Hence why this directory is empty, we need to chose which lib to use.
