First, you need a 9 pin serial crossover cable to hook-up the two
computers.  Typically you'll find a 9 pin serial cable at Radio Shack
and with an optional crossover adapter that plugs into one end of the
cable.

I prefer kermit (instead of minicom -- kermit acts more like a common
shell)

Set /dev/ttyS? to your specific port number.
baud_rate can be set to whatever value you want. (This value is limited
by serial cable length.)

* On the box being used to monitor the target box *
~/.kermrc
set modem type none
set line /dev/ttyS0
set speed 115200
set flow rts/cts
set carrier-watch off

Ensure that baud_base is set to match the remote target box's baud_base
(can be any other supported baud_rate ie 9600):
roger@remote # setserial -a /dev/ttyS0

baud_base <> match the remote target box's baud_rate?
roger@remote # setserial ttyS0 baud_base 115200

* On the target box *

To test that it does work with your working kernel do something like the
following:

/etc/lilo.conf
image = /boot/blah
    label = blah
    root = /dev/hda1
    append = "console=ttyS1,115200"
This will spit-out the dmesg on boot to the remote box.  This is what
you basically want to occur with Linuxbios.  This config option is found
within the config file when building the actual linuxbios image file for
burning to a mtd device (ie flash, DOC, etc)

Or, add to /etc/inittab:
S1:12345:respawn:/sbin/agetty ttyS1 -L 115200 vt102
Restart inetd and this inittab addition will only display the later part
of the boot process and will give you a login shell via kermit/minicom.

Ok. After making sure that your port numbers and baudrates are correct,
fire up kermit on the remote box.  Reboot or restart initd depending on
which test method you decide to choose.

Inclusion here. To have the /etc/inittab file to be re-read:
# telinit q

(i also recall doing a "# killall agetty" for some reason)

The entire specifics of this can also be found in the "Remote Serial
Console HowTo"

After doing:
# kermit

type "connect" (most times, you'll also need to type "RETURN" to get
the shell to display the login prompt).  Type "ctrl \ c" & the "exit".

well, anyways, half of my post here is OT but should help-out.  I'm
also noticing I'll probably confuse any readers. oh well.
