Yes, it works fine on F17.

They actually wrote a specialized telnet client on the Unix side which needs to be supported.  The client side is automated with no human input.  This is a hack written over 15 years ago when the server side was a mainframe running a proprietary OS.  Instead of rewriting things to support new uses they continued down the path they knew.

Yes, we have PHB's in Taiwan too.  :-(
