Given this, I'd suggest one of two approaches (with the same end goal):
1) build everything bottom-up cleanly, like I did, and never set a high
latency timer
OR
2) get some basic code working with a very high latency timer (sounds like
64 might be good. think the max is 255), and then insert all your sync code
later when you want to speed things up
I wouldn't suggest leaving the latency timer high forever, because that's
not a solid fix. I mentioned it just to get you off the ground, if
possible.

You might also try the "send immediate" byte, and see if answers pop up when
you send that, too. I don't remember.
