He's talking OGC side of the equation.  You have to have something to
respond to your rs-232 commands.  The board on bootup would have
almost zero smarts.  So board wise the serial commands just end up in
a RX register.  You have to have code that reads those commands and
does somthing.

I supose that with a proper linux driver (which if it was a 16550
would be really easy to write) then you could drop a serial console on
the port and have access to your linux system.  From there run a
config utility that would set stuff up.

That sound feasable?
