EchoServer based on ChatServer, appending strings to output

Awesome!

Hello, client!
hello
hello +OK

The server seems to be returning the cursor to the next line with no carriage return.

I'll need to to some more debugging, but this has got me on the right track, thank you so much!

I don't really understand why

      if(thisChar == '\n') server.print(" +OK");
      if(thisChar != '\r') server.print(thisChar);

puts the " +OK" after thisChar, since one comes after the other...
