测试Java串行端口程序

我做的代码来读取串口ports.The问题字节流的是我不能因为我没有与这些端口进行交互的设备，以测试代码..测试Java串行端口程序

我已经使用模拟器但上运行的代码和仿真器什么happens.There没有进步，没有错误。

下面是代码

class SimpleRead implements Runnable, SerialPortEventListener{ 
    CommPortIdentifier portId; 
    Enumeration  portList; 
    InputStream   inputStream; 
    SerialPort   serialPort; 
    Thread   readThread; 

    /** 
    * Method declaration 
    * 
    * 
    * @param args 
    * 
    * @see 
    */ 
    public void main(String[] args) { 
    boolean   portFound = false; 
    String   defaultPort = "/dev/term/a"; 

    if (args.length > 0) { 
     defaultPort = args[0]; 
    } 

    portList = CommPortIdentifier.getPortIdentifiers(); 

    while (portList.hasMoreElements()) { 
     portId = (CommPortIdentifier) portList.nextElement(); 
     if (portId.getPortType() == CommPortIdentifier.PORT_SERIAL) { 
     if (portId.getName().equals(defaultPort)) { 
      jTextArea1.setText("Found port: "+defaultPort); 
      portFound = true; 
      SimpleRead reader = new SimpleRead(); 
     } 
     } 
    } 
    if (!portFound) { 
     jTextArea1.setText("port " + defaultPort + " not found."); 
    } 

    } 

    /** 
    * Constructor declaration 
    * 
    * 
    * @see 
    */ 
    public SimpleRead() { 
    try { 
     serialPort = (SerialPort) portId.open("SimpleReadApp", 2000); 
    } catch (PortInUseException e) {} 

    try { 
     inputStream = serialPort.getInputStream(); 
    } catch (IOException e) {} 

    try { 
     serialPort.addEventListener(this); 
    } catch (TooManyListenersException e) {} 

    serialPort.notifyOnDataAvailable(true); 

    try { 
     serialPort.setSerialPortParams(9600, SerialPort.DATABITS_8, 
         SerialPort.STOPBITS_1, 
         SerialPort.PARITY_NONE); 
    } catch (UnsupportedCommOperationException e) {} 

    readThread = new Thread(this); 

    readThread.start(); 
    } 

    /** 
    * Method declaration 
    * 
    * 
    * @see 
    */ 
    public void run() { 
    try { 
     Thread.sleep(20000); 
    } catch (InterruptedException e) {} 
    } 

    /** 
    * Method declaration 
    * 
    * 
    * @param event 
    * 
    * @see 
    */ 
    public void serialEvent(SerialPortEvent event) { 
    switch (event.getEventType()) { 

    case SerialPortEvent.BI: 

    case SerialPortEvent.OE: 

    case SerialPortEvent.FE: 

    case SerialPortEvent.PE: 

    case SerialPortEvent.CD: 

    case SerialPortEvent.CTS: 

    case SerialPortEvent.DSR: 

    case SerialPortEvent.RI: 

    case SerialPortEvent.OUTPUT_BUFFER_EMPTY: 
     break; 

    case SerialPortEvent.DATA_AVAILABLE: 
     byte[] readBuffer = new byte[20]; 

     try { 
     while (inputStream.available() > 0) { 
      int numBytes = inputStream.read(readBuffer); 
     } 

     jTextArea1.setText(new String(readBuffer)); 
     } catch (IOException e) {} 

     break; 
    } 
    } 

}

注：我使用javax.comm和NetBeans IDE。谢谢

直到你有实际设备的可能性不大，我们可以帮助你。在提出这个问题之前，我不得不因此而无法进行所需的研究。 – 2012-08-16 12:26:33
