title: serial port send/receive wrong character
body: <p>I want to set up a serial link between my old zaurus and my pc, here is the pinout for the zaurus :
    <a href="http://www.geocities.jp/tedmiy/ppphsl.html" rel="nofollow">http://www.geocities.jp/tedmiy/ppphsl.html</a></p>
  
  <p>I used the ttl-to-usb converter to connect the pin 3,4,15 of the zaurus, but when I try to send data with minicom to the other side, I always got the wrong character(same with zaurus to pc or pc to zaurus), below is the table(left colcum is the key I pressed, right column is the character I get, N/A means scrambled code)</p>
  
  <ul>
  <li>a -> O </li>
  <li>b -> '</li>
  <li>c -> N</li>
  <li>d -> N/A</li>
  <li>e -> M</li>
  <li>f -> &amp;</li>
  <li>g -> L</li>
  <li>h -> tab</li>
  <li>i -> K</li>
  <li>j -> %</li>
  <li>k -> J</li>
  <li>l -> N/A</li>
  <li>m -> I</li>
  <li>n -> %</li>
  <li>o -> H</li>
  <li>p -> N/A</li>
  <li>q -> G</li>
  <li>r -> #</li>
  <li>s -> F</li>
  <li>t -> N/A</li>
  <li>u -> E</li>
  <li>v -> "</li>
  <li>w -> D</li>
  <li>x -> N/A</li>
  <li>y -> C</li>
  <li>z -> !</li>
  </ul>
  
  <p>both sides are using the same setup, I have no  idea whats wrong...</p>
