The power cube that came with my Hayes 1200 Smartmodem has a connector like:
    ______
  /   o   \    I just measured approx. 12 volts AC (not DC) between the two
 |  o   o  |   lower contacts and zero between the top contact and either

               good guess, but it's not connected to the ground connector of
               the 120-VAC plug-in.
My $0.02.
