That's the SuckyIO serial port. Randolph and I exchanged notes offline
and concluded his prototype C3000 has PA8500 v2.0 CPU (and newer elroys
than mine). I can't reproduce the problem with a v2.3 chip.  I should be
able to upgrade his CPU to v2.3 and we'll see if the problem persists.
Lots of bugs in pre-2.3 chip revisions.
(BTW, does that answer your question Helge? :^/)
