Yeah, you can't generally run fconfigure on $res here because $res is a 
an expect spawn_id, not a Tcl file channel.

[I *think*] You can get a file channel by using:

set fc [exp_open -leaveopen -i $res]; # WARNING: I have zero experience 
with this. I read about it in the expect man page.
fconfigure $fc -translation ...

Another thing that might be worth investigating with is expect's 
built-in stty command.

I am planning on playing with mingw testing this week. At the very 
least, I hope to duplicate some of your problems!
