How to trigger an event when the last data was read from COM port after a certain time with C#?
Is it possible?

The while loop stop when data reads x, but the buttonTransfer button never gets enabled
and the MessageBox message never shows up, but the program does not either freeze. What can be the problem with this code?

try
{
  buttonTransfer.Enabled = false;
  port = new SerialPort();
  port.BaudRate = 9600;
  port.PortName = getValueNew;
  port.Open();

  port.Write("1");

  while (data != "x")
  {
     data = port.ReadLine();
     this.Invoke(new EventHandler(displaydata_event));
  }
  buttonTransfer.Enabled = true;
  MessageBox.Show("Done!");
  port.Close();
}
catch (Exception ex)
{
   MessageBox.Show(ex.Message);
}
