      See my post about the handshaking line / jumper thing.

      AUTOBAUD's always been somewhat experimental. The problem is that it
      switches only when it detects 'noise' or framing errors, beyond a
      certain threshold in a given amount of time. If you're sending it a
      single character (like a carriage return) it can get stuck in the wrong
      baud rate if the combination of the character being sent and the rate
      it's being sent at doesn't result in enough errors.

      It's reasonably good at locking on (sooner or later) to steady data
      streams like a Peet Bros station or a GPS receiver, which makes it
      useful for switching back and forth between two devices like that.
