The Headless Serial Console
I would like to set up a serial console. I would like to be able to
issue LILO boot commands on the serial console. Eventually, if all goes
well, I'd like the machine to be totally headless. If you could give me
a hands-on ``how to do this'', it would be great. I have already read
your ``Serial Terminal as Console'' (Issue #36, April 1997) article, but
I don't get the LILO prompt on my terminal.

This is not a problem at all. If you run kernel 2.2 or 2.3, just
configure serial console support and read
Documentation/serial-console.txt. If you run 2.0, you must apply the
serial-console patch ()
and fall back to the previous case. To use LILO on the serial port, just
add serial=0,9600n8 or an equivalent line to the /etc/lilo.conf file. In
order to interact with LILO, you'll need to send a ``break'' character.

Here are the relevant two lines from my lilo.conf file for serial port
1: 
append="panic=40 console=ttyS0,38400n8 console=tty0"
serial=0,38400n8
On my machine, I had to disable hardware flow control for minicom to
interact with the lilo prompt over the serial port.
