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.
