title: Javascript interface with RS-232 Serial Port
body: <p>I am currently working on a project that involves a 4 Port A/V switch.  This switch can be controlled via RS-232.</p>
  
  <p>The computer that will interface with the switch runs Vista.  I would like to create a sidebar gadget that has 4 buttons- 1 for each port on the switch.  When the user presses the button, it switches to that port.  </p>
  
  <p>I have done a bit of googling, and it seems that there isn't a very good way to interface between javascript and rs-232.</p>
  
  <p>Does anyone have any suggestions for me?</p>
  
  <p>Thanks!</p>
