+    \example creader
+    \title Command Line Reader Sync Example
+    \ingroup qtserialport-examples
+
+    The Command Line Reader Sync example shows how to use the QSerialPort class for
+    receiving data synchronously over the selected serial port with the desired
+    settings.
+
+    \image creadersync-example.png Screenshot of the Command Line Reader Sync example
+
+    This command line reader sync example receives data synchronously over the
+    selected serial port in a console, provided by the QSerialPort class.
+
+    For receiving data synchronously over the selected serial port, use the
+    \l{QSerialPort::read()}{read()} or \l{QSerialPort::readAll()}{readAll()},
+    and \l{QIODevice::waitForReadyRead()}{waitForReadyRead()} methods.
