Shouldn't be too hard to force to back into KISS mode.
The logic I'm using in YAAC is just
Obviously this isn't my actual Java code, but a scrap of pseudo-code, but the concept should be obvious; I don't wait for prompts or acknowledgements, I just do it.
After all, what can my app do if the TNC refuses to cooperate, except call for wiser human assistance?

be much better if Kantronics would FIX THEIR BUGGY FIRMWARE! (I know, shouting
on the internet doesn't mean that the Kantronics engineering staff will hear me
and do what we pay them to do, but it's worth a try).
