Hi,

On my Windows system, I have Cygwin setup, with Emacs as part of the Cygwin
installation. I also setup my Cygwin environment to use zsh. I started my
Emacs from this zsh environment. I think that's where org inherited this
setting.

I think when org execute my block, it some how assumed that it should use
the same shell at the remote end.

P.S. OpenWRT is the router OS. It is just a tiny Linux. Most people would
not install zsh on it :P
