This is what I have in my notes:
The pin out sequence is:
Mod Plug 25 DB male
1 to 22
2 to 6 and 8
3 to 20
4 to 7
5 to 3
6 to 2
7 not used
8 not used
The connections are as follows
RJ45 (9Pin Female)
1 9
2 8,6,1
3 4
4 5
5 2
6 3
So there are two separate pinouts, one for a DB-25, the other for a DB-9.
Hope this helps.
