Setup of console port questions


the following files have been modified to support the rear console port on an Intel server, running Redhat Linux. Connection to the port is via a terminal server. I see output messages being sent to the port on the terminal server, but the port does not respond to my keyboard.

Any ideas would be appreciated.

cat grub.conf

# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.

# initrd /initrd-version.img
#boot=/dev/sda

# inittab This file describes how the INIT process should set up

# Author: Miquel van Smoorenburg, <miquels@drinkel.nl.mugnet.org>
# Modified for RHS Linux by Marc Ewing and Donnie Barnes

# Default runlevel. The runlevels used by RHS are:
# 0 - halt (Do NOT set initdefault to this)
# 1 - Single user mode
# 2 - Multiuser, without NFS (The same as 3, if you do not have networking)
# 3 - Full multiuser mode
# 4 - unused
# 5 - X11
# 6 - reboot (Do NOT set initdefault to this)

What do you mean by terminal server? Is this a dumb terminal or a computer running some kind of terminal software like hyperterminal or minicom?

I assume by your statement that you see the output messages that you can actual read the text.
This means the serial port settings are correct for the "terminal server". It could be a wiring problem with the serial cable. There is a seperate wire for transmit and receive. The "terminal server" transmit wire might be bad.
