Saved my life a couple of times, when LNP was locking up the system in
an entirely incomprehensible way. (I'd really appreciate "Unreachable
code" warnings sometimes... or maybe they scrolled away.)

How about this: a short button press changes to the next sensor, whereas
keeping the button down slowly cycles through the sensor modes? Saves us
from combinations like Ctrl-Alt-Del and the like ;-)

Clear them, of cause.

Once you're interpreting special symbols like \n, you might as well use
the decimal dots where they're available, and interpret "m" as "nn", "M"
as "NN" and so on.
Two seperate printfs would be overkill. I'd prefer a strprintf, or
rather a strnprintf for security. Fine for the current state of
networking, and cprintf would be a mere wrapper then, as output niceties
are handled in cputs.
