LoopbackB.setConsole() InternalError in TCP connection (Espruino WiFI)

Ok, I removed the data event.

Now, on connecting I get a lot of garbage, something like:

▒ ▒ ▒▒''▒ ▒ ▒▒▒'▒' ▒▒' ▒ ▒ ▒ ▒▒▒'▒' ▒▒' ▒ ▒ ▒ ▒▒▒'▒' ▒▒' ▒ ▒ ▒ ▒▒▒'▒' ▒▒'▒▒▒▒▒▒'
▒▒▒'▒▒'   ▒ ▒ ▒▒▒'   ▒▒'   ▒ ▒ ▒▒▒'   ▒▒'   ▒ ▒ ▒▒▒'   ▒▒'   ▒ ▒ ▒▒▒'   ▒▒'
:▒▒▒▒'

I also modified the try/catch block like this:

try{
      LoopbackB.setConsole();
    } catch(e){
      USB.write("LoopbackB.setConsole(): " + e.type + " " + e.message + " " + e.stack);
    }

and on connecting putty, the IDE shows the "setDeviceClockCmd" error, so it's still there.
