Believe it or not, open('CON:','wb') actually works under WinXP. It's 
amazing that this relic from DOS is still around. Though unportable (the 
Unix equivalent is open('/dev/stdout','wb')) and ugly, it'll get the job done.

Optimally, you'd want to use something like C's freopen to re-open 
sys.stdout in binary mode, but I can't find anything like it under the os 
module. Does Python not have this ability?
