Re: Where are my serial ports?

[Jeff Adams <jadams@hoovers.com>]

Thanks for the input. Unfortunately, there doesn't appear to be any 
serial port info in the boot messages, at least none in a form I'm used 
to seeing.

I'm almost convinced that the serial ports have somehow been disabled, 
but I can't figure how that would have been done, or more importantly, 
undone.

Thanks again,

- Jeff
