It looks like the NT command shell isn't an ANSI terminal.

Back in the DOS days, I'd have said "put DEVICE=ANSI.SYS into your config.sys", but to tell you the truth I have zero clue how you can make cmd speak ansi...

If you tried it with a colour xterm to a unix box, I'll bet it'll work...

Hmm, in fact, it works with Cygwin bash shells; they speak ansi colour codes, it looks like.
