The new packet expects an immediate response.  The remote protocol could
have gone in two different directions here - drop the ack, always
require the ack - and you've chosen the later and that definitly doesn't
worry me :-)

What I'm trying to understand is how this packet will interact with
other things such as that out-of-band output (``O'') packet that comes
from the target.  Ditto for an input packet if that is ever created.
