Ok, so the issue is that the telnet tool itself seems to send a whole bunch of weird characters when it connects (they are part of the actual telnet protocol). Something along the lines of:
```
\xFF\xFD\x03\xFF\xFB\x18\xFF\xFB\x1F\xFF\xFB \xFF\xFB!\xFF\xFB\"\xFF\xFB'\xFF\xFD\x05\xFF\xFB#
```
These really confuse Espruino as they're fed right into the console, and Espruino doesn't know to ignore them.

However if you connect using the Chrome App IDE (communications -> connect over TCP address) it won't send the characters and everything works great.

You can also use putty on Windows - just set the connection type to 'raw' when you connect.
