Re: minicom -> dumb terminal?

Yes. I wanted to be able to compile and test a kernel on a remote Linux
server, so I had to be able to use Lilo in case the fresh kernel
couldn't boot the machine.

If you configure your kernel, say yes to:
Support for console on serial port
CONFIG_SERIAL_CONSOLE
If you say Y here, it will be possible to use a serial port as the
system console (the system console is the device which receives all
kernel messages and warnings and which allows logins in single user
mode). This could be useful if some terminal or printer is connected
to that serial port.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttyS1". (Try "man bootparam" or see the documentation of
your boot loader (lilo or loadlin) about how to pass options to the
kernel at boot time. The lilo procedure is also explained in the
SCSI-HOWTO, available via FTP (user: anonymous) in
ftp://metalab.unc.edu/pub/Linux/docs/HOWTO.)
If you don't have a VGA card installed and you say Y here, the
kernel will automatically use the first serial line, /dev/ttyS0, as
system console.
And I have this in /etc/lilo.conf on the remote machine:
[cut]
vga=normal
delay=20
default=2.2.7
serial=0,9600n8
append="console=ttyS0
[cut]
Hth. Good luck! It's a nice feature.
