The terminal emulator is ultimately responsible for setting TERM
appropriately, and usually does. The only problem is with TERM=xterm vs.
TERM=xterm-color -- most xterms (including rxvt) will use the former as
the default TERM value. You can override the TERM value that xterm or
rxvt sets via command-line options or X resources, though.
If you spawn a "DOS-like shell" (by which I assume you mean a bash running
in a Windows console window), TERM is automatically set to "cygwin". You
can use that fact in your scripts to change it to "ansi" if you wish.
To my knowledge, it is not possible in general to automatically detect the
remote TERM type.
