60 /****
61 * This is an example of a trivial use of the TelnetClient class.
62 * It connects to the weather server at the University of Michigan,
63 * um-weather.sprl.umich.edu port 3000, and allows the user to interact
64 * with the server via standard input. You could use this example to
65 * connect to any telnet server, but it is obviously not general purpose
66 * because it reads from standard input a line at a time, making it
67 * inconvenient for use with a remote interactive shell. The TelnetClient
68 * class used by itself is mostly intended for automating access to telnet
69 * resources rather than interactive use.
70 * <p>
