title: How can I use a raw_input with twisted?
body: <p>I am aware that raw_input cannot be used in twisted.  However here is my desired application.</p>
  
  <p>I have an piece of hardware that provides an interactive terminal serial port.  I am trying to connect to this port and send commands in an async manner.  I need it this way because this is a motor controller that once I issue a command it will "block" and run away (my current code).  I need to be able to enter another command such as ESTOP in case of problems or danger. </p>
  
  <p>I have read some stuff about <code>twisted.internet.stdio.StandardIO</code> however I have not had much luck..
  Any advice / help on this would be great.</p>
