Yeah, it really makes things much nicer doesn't it?

Instead of a DataInputStream and DataOutputStream, use an 
InputStreamReader and an OutputStreamWriter.

ReadUTF expects a 2-byte length at the front of the string, which is 
hard to send with Telnet.  For this approach, you would use normal 
Readers and Writers, and write code as if you are talking to a 
terminal.
