Hey GnomeBoy --
I'm not a Cisco guru and I don't pretend to be one, but you might give this a shot:
Hope that helps!

I see this request is from June, I sure hope this person found the answer before now. But, since there seems to be conflicting information, I'll be sure to throw mine in.
I grabbed the cisco blue 8 pin modular cable (which is reversed like a phone cable) and the matching 74-0495-01 TERMINAL DB9 Female to modular 8 pin adapter from the truck and here is what I found:
Opening up the modular adapter and physically tracing each wire, here is how it is made up:
DB9F Pin - Wire Color - 8 pin jack
1 - No Connection
2 - yellow - pin 6
3 - black - pin 3
4 - orange - pin 2
5 - green+red - pins 4 and 5
6 - brown - pin 7
7 - blue - pin 1
8 - white - pin 8
9 - No Connection
Now that is the combination you need IF you are going to make another DB9F to modular adapter.
To take it one step further, I plugged in the modular cable and checked pin for pin, so if you were to make up a dedicated cisco terminal cable, these are the pins on the rear of the cisco unit and their associated DB9F pin.

Rear Panel DB9 Female
1 --------------- 8
2 --------------- 6
3 --------------- 2
4 --------------- 5
5 --------------- 5
6 --------------- 3
7 --------------- 4
8 --------------- 7
From this, we can glean the following information about the back panel modular CONSOLE jack on the cisco:
Pin 1 - RTS
Pin 2 - DTR
Pin 3 - TX
Pin 4 - Ground
Pin 5 - Ground
Pin 6 - RX
Pin 7 - DSR
Pin 8 - CTS
Good Luck!
It is only my opinion, based on my experience and education...I am always willing to learn, educate me!

Hello,
I have cable internet right now with a linksys router. Also I have a CIsco 2524 router I'd like to hook up to my cox cable modem. Thing is I have no serial modules in the back of my router. Where would I find one of these, and would I also need a adapter to connect to rj45?
Thanks Joe Another Child of God

What is the db9 wiring for a fibre channel hba t-card dual port look like? I have one port running at 1Gbyte sec. . I want to figure out how to wire the second port so I access the drives from a second p.c. host bus adapter on the second port. using sca40's on the fibre channel drives t-cards. I have 2 different t-cards and am looking at making my own using schematics and parts as I have quite a few drives to hook up and am on low budget. I checked out overclockers, etc. and they have pictures, schematics, etc. but I would like to post the projects when done so others can use them.
