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