cu: /dev/ttyS0: Line in use

[listmail@rotundus.com]

At this point I think I've about run out of ideas as to what could be
causing such an error, as a short while ago I was able to make a
connection using the serial port.

What I'm trying to do is configure a terminal server, and I need to get
access to it through a serial port to configure its network interface.

The particular machine I'm using supports serial console redirection, but
I've disabled that in the bios.  I also removed the flags in the boot
loader that redirect output to the serial port upon system boot, and also
disabled any console running there in /etc/inittab.

At the moment 'lsof | grep /dev/ttyS0' doesn't return anything.

Just in case the terminal server itself (which was reset to factory
defaults for a reinstall), somehow was attempting to make a connection to
the particular serial port in question I powered it down, but that made no
difference.

Can anyone suggest anywhere else to look for the source of the problem?
