It never seems to work after I've used emptool.

Exactly. The serial port has been used for the protocol so it is in raw mode.

You can use emptool to quit the player if you need to.

I'm not keen on using the remote to quit the player since there are far more important uses for all the buttons. Also, it would be useless on the consumer image.

It is possible that the port could be reset to cooked mode after synchronisation is complete but this is quite difficult to manage.
