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

Hi,
Same problem here, I am trying to create a remote Telnet connection, similar code as the first post from Steffen, but it doesn't work.

I have Spruino Wifi 1.99 and connect to port 23 with Putty.

If I send something like:

conn.write('Welcome!\r\n');

I see it in Putty, but the terminal does not respond to my keys.

If I set an event like:

conn.on('data', function(data) {
      USB.write('client says: ', data);
});

The text entered on putty is printed on the IDE, so the connection is working.

Maybe Loopbacks are not working?

Thanks Gordon
