boolean True to keep watching for events, false to stop.

onUartDeviceError

void onUartDeviceError (UartDevice uart, 
                int error)

Called when an error occurs with the interrupt event listener. At this point the receiver should assume that this UART is no longer usable. No further callbacks will be received on this object.
