[SGVHAK] Raspberry Pi Serial Console

[Claude Felizardo]

My first SD card stopped working suddenly - i thought I had damaged my
Pi after swapping power supplies.  It just sat there, no flashing
lights, just the too bright power LED glaring at me. This was a few
months ago so I don't recall if i simply flashed another SD or reused
it but it was working the last time I tried it.  I am concerned about
corruption after a power outage but have not had a chance to get back
to the Pi in a while.  Been busy with a certain compiler class -- Hi
Dustin!
