使用SerialPort類讀取連接設備的響應

我正在使用C＃的SerialPort類嘗試向設備發送「AT」命令並獲取響應。我已經驗證了它在超級終端中的正常工作，如果我發送了一個「AT」命令，它會迴應「OK」。但是，在我的控制檯應用程序中，如果我發送「AT」，它將回送回「AT」。代碼如下，任何見解，我在我的接收代碼做錯了什麼，將不勝感激：使用SerialPort類讀取連接設備的響應

ComPort.DataReceived += new SerialDataReceivedEventHandler(ComPort_DataReceived); 

public void Open() 
     { 
      Console.WriteLine(); 
      //close port if already open. 
      if (ComPort.IsOpen) 
      { 
       ComPort.Close(); 
      } 
      //setup port. 
      ComPort.PortName = ConfigurationManager.AppSettings["PortName"].ToString(); 
      ComPort.BaudRate = Convert.ToInt32(ConfigurationManager.AppSettings["BaudRate"]); 
      ComPort.Parity = Parity.None; 
      ComPort.StopBits = StopBits.One; 
      ComPort.DataBits = 8; 
      ComPort.DtrEnable = true; 
      ComPort.RtsEnable = true; 
      if (Convert.ToBoolean(ConfigurationManager.AppSettings["HWFlowControlEnabled"])) 
      { 
       ComPort.Handshake = Handshake.RequestToSend; 
      } 
      //open port. 
      Console.WriteLine("Opening port " + ComPort.PortName + "..."); 
      ComPort.Open(); 
      Console.WriteLine("Opened port " + ComPort.PortName); 
     } 

void ComPort_DataReceived(object sender, SerialDataReceivedEventArgs e) 
     { 
      string message = ComPort.ReadExisting(); 
      Console.WriteLine("RECEIVED: " + message); 
      if (message.IndexOf("OK") > -1) 
      { 
       ReceivedOK = true; 
      } 
     }
