  Connect to hub v1 via sockets on a configurable port. Default port is 9761. Move from serial.aio to serial_asyncio to provide proper support for sockets and Windows.

This change caused things to break for me:

transport, protocol = yield from create_serial_connection(
                    self._loop, lambda: self.protocol,
                    self.device.upper(), baudrate=19200)

with this exception:

serial.serialutil.SerialException: [Errno 2] could not open port /DEV/TTYUSB0: [Errno 2] No such file or directory: '/DEV/TTYUSB0'

A previous version did some test about os.name == 'nt' which only did the upper() if you are windows. I think this needs to test whether or not it needs to do that conversion again.
