     * Implementation of a CAN driver handling RTR is much more complex. On some controllers impossible.     * Implementation of a CAN driver handling RTR is much more complex. On some controllers impossible.
     * Some CAN controllers react different on the 'data length' code in the RTR frame and the data frame. This is due to differences in the CAN implementation.  \\     * Some CAN controllers react different on the 'data length' code in the RTR frame and the data frame.
