  Telnet client

 This sketch connects to a a telnet server (http://www.google.com)
 using a DigiX.  You'll need a telnet server
 to test this with.
 Processing's ChatServer example (part of the network library) works well,
 running on port 10002. It can be found as part of the examples
 in the Processing application, available at
 http://processing.org/
