|
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. |
