Serial port console install

Pay particular attention to:
Headless server settings
Slackware had all this stuff commented out in the /etc/inittab file,
but RedHat you have to add it.
Also, you will need to learn what type of terminal, cable, adaptor,
etc you need to make it communicate with a dumb terminal. For a dumb
terminal you need a special cable or an adpator, in most cases RST,
CST, etc. Search for the Linux Serial howto. There are pages online
with photos on how to setup the hardware. In other words, if you use
a standard serial cable, you need an adaptor. I think you need a
crossover cable, but it's been years since I setup a dumb terminal and
logged in via serial port. There are also adpators you can make which
use standard cativ twisted pair ethernet! It's very very tricky;)
