Thanks for the valuable info. Since I'm using Redhat 7.3, I have slightly
setup than yours to make it work (on Linux system only).

1. In /etc/inittab, add

T0:2345:respawn:/sbin/agetty -L 9600 ttyS0 vt100

2. In grub.conf, add

"console=tty0 console=ttyS0,9600n8"

3. Reboot the system

Now, if I issue "cu -l /dev/ttyS0" on another Linux system, I can get login
prompt.

However, if I issue "cu -l /dev/cuaa0" on FreeBSD system, I got the
following
error messages:

cu: open (dev/cuaa0): Permission denied
cu: /dev/cuaa0: Line in use

I have no idea why I was getting this error.

Any idea?

Yang

I did this recently on Debian and Red Hat, I think it was as simple as:

1. edit /etc/inittab and un-comment (or add) a line like this:

T0:23:respawn:/sbin/getty -L ttyS0 9600 vt100

2. add ttyS0 to /etc/securetty

3. reload inittab with 'init q'

If when you originally installed you booted with 'console=ttyS0,9600n8'
I think it will actually set this all up for you.  You can always add
this to your bootup with lilo/grub/etc. depending on which you use.
