i have just inherited a HP/Compaq Proliant ML530 (Generation 1) server.
Ive got it configured, and got RHEL 5.x running nicely on it. But i want it to be headless. SSH is ok, but in the event that the network goes down or something I would like to have a plan B. And I have an old dumb terminal sitting doing nothing. So how to configure a serial console on the server?
