Re: Progress and Wiki

Hello Andrew,

I dumped all the GPIOs in b (not plugged in) and c (plugged in) and
compared both dumps:

Here's the result:

It seems that GPIO 11 goes from 1 to 0 when the serial cable is plugged in.

Does this make sense? I hope this helps...

Sorry if I'm not familiar yet with GPIOs... Anyway, don't hesitate to
ask me do make any dump that would be needed....

Cheers,

   Michael.
