恢复SerialPort连接（jSerialComm）

Question

我使用jSerialComm库从Arduino获取数据。如何跟踪与Arduino的通信中断并在可能的情况下将其恢复？以下是与SerialPort相关的部分代码。

SerialPort comPort = SerialPort.getCommPorts()[0];  
comPort.openPort();
comPort.setComPortTimeouts(SerialPort.TIMEOUT_READ_SEMI_BLOCKING, 0, 0);
final Timer t = new Timer(100, null);
t.addActionListener(new ActionListener() {
    int countBanana = 0;
    int CheckLife=0;
    int b;
    int c;
    String s = null;
    @Override
    public void actionPerformed(ActionEvent e) {
        try {
            {
                while (comPort.bytesAvailable() == 0) {
                    try {
                        Thread.sleep(20);
                    } catch (InterruptedException e1) {
                        e1.printStackTrace();
                    }
                }

                byte[] readBuffer = new byte[comPort.bytesAvailable()];
                int numRead = comPort.readBytes(readBuffer, readBuffer.length);
                System.out.println("Read " + numRead + " bytes.");
                System.out.println(String.valueOf((char) readBuffer[0])+String.valueOf((char) readBuffer[1])+String.valueOf((char) readBuffer[2]));
                c = Integer.parseInt(String.valueOf((char) readBuffer[0])+String.valueOf((char) readBuffer[1])+String.valueOf((char) readBuffer[2]));
            }}
            catch (Exception m){}
            if(c<101){
                b = c;
            }
