Help - how to install Solaris T42 via serial port

I did some unix admin many years ago, but since then I have been programming. I now have to install solaris 10 on a T42 via a console/serial cable.

Could anyone please provide some help on the following.

We have one solaris server up and going, I use Cygwin to get to this (xwin -query ...) and start a terminal window. These two servers are connected with a serial cable.
How do I connect to the T42 from this console window ?, I seem to remember /dev/tty.. and a tip command ? 9600 N 8 Y or something similar.

Do I then get to the OK> prompt from the # prompt

OK>boot dvd/cdrom ?

Where does the lom come into this?

Regards

Connect a RS-232 terminal (or PC with terminal emulator) via a serial cable (DB9 to RJ45) to the ser-mgt port. Alter the baud rate until you get OK prompt. Probably need to set to 9600-8-N-1

How about reading the really fine documentation?
