/***
* This is an example of a trivial use of the TelnetClient class.
* It connects to the weather server at the University of Michigan,
* um-weather.sprl.umich.edu port 3000, and allows the user to interact
* with the server via standard input. You could use this example to
* connect to any telnet server, but it is obviously not general purpose
* because it reads from standard input a line at a time, making it
* inconvenient for use with a remote interactive shell. The TelnetClient
* class used by itself is mostly intended for automating access to telnet
* resources rather than interactive use.
