Enabling Serial Console

[mailing lists at MacTutor]

Marc,

Try putting either '-h' or '-D' in /boot.config. I found '-D' worked 
for me. Personally, I'm wondering if I can put together a serial 
multiplexer to USB device and write a C or Perl script that will tee 
the output to respective files that I can 'tail -f' on.

For a more thorough treatment in a non-intuitive place checkout the 
Handbook:
