All,

Solution:

At SRM prompt,
P00>>> set console serial
P00>>> init

This enabled our DS10 to use the COM port.

Embarrassingly, the ES40 was connected to the 9-pin modem port, should be
connected to the MMJ (com 1) port. I must save face by saying this server
is remote and I was relying on local guy to look at back of server for me!
;)

For our ES40, the correct cable was located and that works fine now.

Once again, thanks for all your replies.

Regards
Shaun

What type of connector do you have on the ES40? I do this all the time with
my laptop, but I use two H8571-J connectors with a decconnect cable.

Set the console variable to serial, init the console and you should be
all set.

You might need to put an entry in the /etc/securettys file like /dev/tty00.
I also added in an entry to the inittab file -
tty00:234:respawn:/usr/sbin/getty /dev/tty00 console vt100. I was having
problems with connecting to a terminal server, and these seemed to fix my
problems.

if you want the console to be serial then yes, you need to set it to
"serial" - this means that you will no longer need to have a video
connected to the graphics card. Normally 9600 XON/XOFF is correct.

Similarly you need to check /etc/inittab to ensure that the relevant
tty is enabled with a getty listening on it otherwise you'll never get
a prompt.

At the console set tt_allow_login to 1
This permits getty to run on the tty0 port

Or you can run getty manually for the tty0 device.

I'll be very surprised if you haven't received an answer to this yet,
but in case you haven't ...

Yes, this is very likely exactly where your problem lies.

Only if the serial port configurations have been changed, but that's
usually not likely. (check that com1_* variables match what you expect,
but unless someone has explicitly changed these, they will.)
