Good question.

I'd probably respond with a STATUS_MESSAGES response (similar to E1.20 section 10.3.1 paragraph 3). That effectively means "I have no queued messages for you".

It's probably best to have no parameter data and set the PDL to zero. This way a status message won't get lost if the controller isn't expecting a STATUS_MESSAGES PID in response to a GET_LAST packet.
