I communicate with a unit to control a satellite antenna via a serial connection. Opening a connection with the serial device: import gnu.io.CommPortIdentifier; import gnu.io.SerialPort; portIdentifier = CommPortIdentifier.getPortIdentifier(device); serialPort = (SerialPort) portIdentifier.open(name, serialPort.setSerialPortParams(baudrate, databits, stopbits, parity); serialPort.setFlowControlMode(flowMode); bufferedReader = new BufferedReader(new InputStreamReader(serialPort.getInputStream)); outputStream = serialPort.getOutputStream; If the unit is becomes unavailable, I have to clear the stream before being able to send new commands, once the device is up again. But this clear method on the input/output stream blocks if the device is down. Also closing the streams, or closing the SerialDevice blocks. Is there a way to close/clear these streams or SerialDevice without blocking? BufferedRead.close; // blocks until device is up again outputStream.close; // blocks until device is up again serialPort.close; // blocks until device is up again.
