Subject: Telnet client

I use ruby wrote a Telnet client application. It works fine until users
want to change a user name or telnet to other host. I found all these
failed operations are related with "su -" command or login. How can I
let ruby deal with these? Below is my core code for this telnet client:

while 1 == 1
  c=gets
  tn.cmd(c){|c| print c}
  if c=="exit"
    break
  end
end

It simply get what user input and put it on the telnet server.
