4.9.0 with shell via telnetd

[gds at chartertn.net (Gene Smith)]

The shell with telnetd in 4.8 works find. Just have to intialize telnetd 
in Init() and it goes.

However, with 4.9 the new improved shell has a documentation hole 
regarding telnet. The shell manual says it easy to attach the shell to a 
serial port or telnetd. However, how to do it with telnetd (a socket) 
says TBD.

Can someone list the steps needed to get telnetd running with the shell 
in 4.9.0 ?

Thanks,
