The last pywin32 release (213) does work with Python 3.
If you can wait a few days, I'm working on a proper port of pyserial.  
Preliminary testing shows it's working fine on Windows. Basically, I've  
modified the read/write methods to use bytes instead of str, and 2to3 did  
the rest:

Python 3.0.1 (r301:69561, Feb 13 2009, 20:04:18) [MSC v.1500 32 bit  
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

ATI7
