[rescue] Sun serial cable pinout question (null modem)

[Gavin Hubbard]

Hi Guys

I'm going to make up some null modem cables for my new Sun systems (using
DB9/25-RJ45 shells).

The two pin-outs that I've seen for the Ultra 2 are:

2-3
3-2
7-7

and

2-3
3-2
7-20
20-7

Are these two equivalent? And for the 2nd setup, what do you do if one end
is a DB9?

Thanks in advance for your help,

Gavin
