First, whenever you post about odd CodeWarrior behavior, you really need to also post the version of the tools you are using, as behavior changes and bugs are fixed from version to version. As best I can tell, this error isn't given by the V9 debugger.

The "No data to read" error means that the debugger was notified that there was a debug packet available, but when it tried to read it, nothing was there. It is an indication that there's a problem in the connectivity between CW and your device, but I can't say specifically what happened.

When I try stepping through the code to find out what might be going wrong,
I reach a point where subsequent calls to EvtGetEvent(..) in my main Event
loop will only generate nilEvents.  CW and POSE don't seem to be connected
anymore at this point -- the Gremlin's event count doesn't increase with
every pass through my main event loop.

If you can step through your code, you're connected -- CW is able to send packets to POSE and it sends back responses. Maybe POSE is faking things, but this is really unlikely.

Sorry about the vagueness of this post.  Because I can't step through the
code up to the problem, I'm having a hard time figuring out what's going on.
