Definitely...reading owners manuals can reveal interesting "tricks".
Holding the "TOC" button (for about 10 seconds) on my 715 during
powerup will force the console to serial port 1.  The user doesn't
have to muck with setting paths for collecting linux kernel output.
Check if the C200+ has the same behavior - good chance it does.

"Legacy" firmware (includes C200+, A180L, etc) run PDC/IODC in narrow mode.
I expect PDC calls to work the same. I think something else is different.
As Philipp suggested, check the PIM dump since it's the only info available.
Someone is looking at a PA debugger...
