023/***
024 * This is an example of a trivial use of the TelnetClient class.
025 * It connects to the weather server at the University of Michigan,
026 * um-weather.sprl.umich.edu port 3000, and allows the user to interact
027 * with the server via standard input.  You could use this example to
028 * connect to any telnet server, but it is obviously not general purpose
029 * because it reads from standard input a line at a time, making it
030 * inconvenient for use with a remote interactive shell.  The TelnetClient
031 * class used by itself is mostly intended for automating access to telnet
032 * resources rather than interactive use.
