Hmm, a few of those are different from what they are on my machine:
ixon -echo -echoe -echoctl -echoke, but changing them doesn't produce
the effect you're seeing. Still begs the question though why they are
different. Any chance there's a mixup with different Cygwin versions
or a different Unix environment?

Otherwise, I'm stumped. I think 'cygcheck -svr' output is needed to
get any further. Please attach, not include it, and make sure you
delete any sensitive info from it first.

Also, what happens if you invoke Cygwin from the desktop or start menu
shortcut? You could also try installing mintty or rxvt to see whether
you get the same problem there.
