These settings are not supported on the serial line.  Basic I/O is
supported, but no cooked mode.  Maybe we can derive the fhandler_serial
class from fhandler_termios instead of from fhandler_base at one point,
but none of the core developers really need and use serial I/O so our
incentive to change that is very low.

Having said that, we certainly appreciate patches to Cygwin's serial
I/O stuff.  See http://cygwin.com/contrib.html
