I modified the win32-openssh client to send "\n" instead of "\r" so the
command gets executed but the per-keystroke echo is not working. 
Example - when I type "dir\n".. At the client side I see the output of
the dir but not the command "dir"..

I tried the same thing on the unix ssh client, it does echo the actual
command "dir".

Is there anything we need to do to show the per-keystroke echo?
