I have no info on the first question, but about the serial interface. The commands above actually run over USB. Simply boot the Neo into uBoot (hold the Aux button while powering on) and select the option to use the console over USB (Move selection using Aux, invoke the selection by pressing power). Then plug in the USB cable and run the "cu" command. - John
