     If \l{QIODevice::}{waitForReadyRead()} returns false, the

+    If an error occurs at any point in time, QSerialPort will emit the
+    errorOccurred() signal. You can also call error() to find the type of
+    error that occurred last.

     Programming with a blocking serial port is radically different from
     programming with a non-blocking serial port. A blocking serial port
     does not require an event loop and typically leads to simpler code.
