           "A control for the port's ability to automatically
           sense input speed.

           When rs232PortAutoBaud is 'enabled', a port may
           autobaud to values different from the set values for
           speed, parity, and character size.  As a result a
           network management system may temporarily observe
           values different from what was previously set."
