Mitutoyo 직렬 통신 데이터 값이 업데이트되지 않음

Mitutoyo 게이지에서 읽은 데이터 값이 올바른지 확인하기 위해 단위 테스트를하고 있습니다. "GA00"명령을 보내고 데이터 값을 다시받은 다음 "CR01"명령으로 첫 번째 채널을 0으로 설정합니다. 그런 다음 "GA00"명령을 다시 보내 채널 1이 다시 0으로 수정되었는지 확인합니다 그것은 변하지 않았습니다.Mitutoyo 직렬 통신 데이터 값이 업데이트되지 않음

그러나 테스트를 다시 시작하면 설정 값이 0으로 변경되고 모두 정상입니다. 데이터를 다시 0으로 설정하는 응용 프로그램/테스트를 다시 시작하면 어떻게됩니까? 내가 알아낼 수 있다면, 나는 단지 내 코드에서 그것을 할 것이고, 나는 좋을 것이다.

도움 주셔서 감사합니다.

내 문제는 내가 읽는 것을이었다 동시에 직렬 포트에 기록하십시오. 동료가 동시성 및 멀티 스레딩을 검토하여이 튜토리얼을 읽도록 제안했습니다. http://tutorials.jenkov.com/java-concurrency/index.html 모든 주제에 대한 자습서를 강력하게 권장합니다. 잘 쓰여지고 따르기 쉽습니다. 궁극적으로 클래스에 클래스를 추가하고 읽기 및 쓰기 부분 (객체와 동기화 됨) 주변의 블록을 동기화했습니다.

고정 코드 :

private final Object mutex = new Object(); 
private void WriteToPort(String send) { 
     try { 
      byte[] commandBytes = send.getBytes(); 
      System.arraycopy(commandBytes, 0, sendCommandBuffer, 0, commandBytes.length); 
      sendCommandBuffer[commandBytes.length] = 13; // CarriageReturn 
      sendCommandBuffer[commandBytes.length + 1] = 10; // LineFeed 
      synchronized (mutex) { 
       out1.write(sendCommandBuffer, 0, commandBytes.length + 2); 
       out1.flush(); 
      } 
      try { 
       Thread.sleep(dataFrameRefreshRate); 
      } catch (InterruptedException ex) { 
      } 
     } catch (IOException e) { 
      logger.log(Level.INFO, "There was an error while writing to the serial port", e); 
      Disconnect(); 
     } 
    } 

@Override 
public void serialEvent(SerialPortEvent event) { 
    if (event.getEventType() == SerialPortEvent.DATA_AVAILABLE) { 
     try { 
      synchronized (mutex) { 
       while (in1.available() > 0) { 
        System.out.print("Getting Input. Available Bytes:" + in1.available()); 
        int numBytes = in1.read(serialBuffer, this.serialBufferLength, serialBuffer.length - this.serialBufferLength); 
        serialBufferLength += numBytes; 
        try { 
         Thread.sleep(dataFrameRefreshRate); 
        } catch (InterruptedException ex) { 
        }
