Issue with logging.config

[Joe Hughes]

Peter,

	Thanks for the information.  I sent an email to the maintainer and got some information that helped me continue with this.  My solution was to change line 785 of handlers.py to

self.socket.sendto(bytes(msg, 'ascii'), self.address)

After I made the change, I got exactly what I was looking for.
