i have this code:

private SerialPort port = new SerialPort("COM1", 115200, Parity.None, 8, StopBits.One);

                  Console.WriteLine("Incoming Data:");
                  port.WriteTimeout = 5000;
                  port.ReadTimeout = 5000;
                  // Attach a method to be called when there is data waiting in the port's buffer
                  port.DataReceived += new SerialDataReceivedEventHandler(port_DataReceived);

                  // Begin communications
                  port.Open();
                  #region PhoneSMSSetup
                  port.Write("AT+CMGF=1\r\n");
                  Thread.Sleep(500);
                  port.Write("AT+CNMI=2,2\r\n");
                  Thread.Sleep(500);
                  port.Write("AT+CSCA=\"+4790002100\"\r\n");
                  Thread.Sleep(500);
                  #endregion
                  // Enter an application loop which keeps this thread alive
                  Application.Run();
