使用Java从串口读取文件

Read file from serial port using Java

提问by

I'm begginner in Java, I'm writing ("FLASH").getbytes()like this to serialport.

我在Java中begginner，我写("FLASH").getbytes()像这样serialport。

After I'll get FLASH_OKas response, again I've to send file request. After that I'll get response as FILE_OKthen I have read file up to end of the file.

在我得到FLASH_OK回应后，我再次发送文件请求。之后我会得到响应，因为FILE_OK我已经阅读了文件直到文件末尾。

I'm not getting how to do this, so please help me.

我不知道如何做到这一点，所以请帮助我。

Thanks for reply.

谢谢您的回复。

Looks like to need a SerialPortReaderwhich needs to implement a SerialPortEventListener

看起来需要一个SerialPortReader需要实现一个SerialPortEventListener

     public void serialEvent(SerialPortEvent event)
     {
            case SerialPortEvent.DATA_AVAILABLE:
            byte[] readBuffer = new byte[40];

            try
            {
                while (inputStream.available() > 0)
                {
                    int numBytes = inputStream.read(readBuffer);
                }
                System.out.print(new String(readBuffer));

                System.out.println();
                System.out.println("DTR: " + serialPort.isDTR());
                System.out.println("DSR: " + serialPort.isDSR());
                System.out.println("CTS: " + serialPort.isCTS());
                System.out.println("RTS: " + serialPort.isRTS());
                System.out.println();
                outputStream.write("ACTIVESYNC".getBytes());
            }
            catch (IOException e)
            {
                e.printStackTrace();
            }
