I installed the latest version today and was able to get things
working.  (It prints out more about issues connecting, which
allowed me to resolve them.)

- The remote end was not setting LANG for UTF-8.  I had to do this
   by: mosh --server='mosh-server new -l LANG=en_US.UTF-8'

- I discovered that mosh does not support an xterm escape sequence
   that I use, namely one to *read* the window icon label: CSI 20 t
   and also CSI 11 t (reports whether the window is iconified).  My
   main purpose is to save and use the icon label as the base for
   setting a longer label or title

I have worked around this by setting an extra environment variable
when using mosh, and skipping the reading of the icon label in that
case.

However, all of this is not really cygwin-specific, so I'll stop
there.

However, the failure to install the IO:Tty dependency may be relevant.
Is there an easy way I can test that again?  What would I uninstall
and reinstall to check?  That is, cpan will install things, but how
would I *un*-install IO:Tty to check whether cygwin install of mosh
loads it?
