Meh.  Sounds like a big CF and security nightmare.

If you're going to do that maybe you don't need conserver.  I have some
"reverse TCP" code I wrote some years back that will do exactly what you
are looking to do.  It emulates the behavior of an old school terminal
server.

Fix it.  I've not looked at the new code but it seems to me that it is
not catching EOF.  I could be wrong.

(sleep 3) | strace console myconsole 2>/tmp/strace.log

What is it doing?
