I think you need ANSI codes for the screen/window.
cygwin contains this in its terminal.
mswin32 seems to not contain it, but adding
	device=c:\....\ansi.sys
could help.

The details about installing devices vary according to whether you use
DOS (or Win95,98) vs. Win ME vs. WinNT (or Win 2k).

Second posibility (citing Tobias Peters <tpeters@uni-oldenburg.de> from
another thread of this newsgroup):
