I've pulled the card out of my Nikon D90 a few times while
it is accessing the card. I can then put it in the PC and
see what the D90 was trying to do.
I've noticed two new commands: one to disable the WiFi on
the card, and the other to check to see if the WiFi is
currently disabled or not.
I haven't hooked these up to the user interface yet.
I also think the 'o' 13 command tells which ESSID the card
is currently associated with. 'o' 12 might be something to
do with pending uploads.
We used to clobber the password that came in from the user
when converting it from ASCII to binary for WEP. That
screwed it up because we need to use it twice: once for
testing, and once for the actual addition.
(it doesn show up in the log when I do this)
Start propogating error codes back from a bunch of
functions. We need this for the CHDK port because
we can't just exit() there.
Add dumping of the firmware version string.
