Hi,

Would this work for you: product 24542M ?
It is a RS-232 Modem Cable 25pin to 9 pin, DB25 male to DB9 female.

You can also view a picture of connection in this doc, http://docs.hp.com/en/J6352-90003/J6352-90003.pdf .
Look at fig 1-2 on p.18.
The cable number is hard to read.

Does this work?

Hello,

If you want to solve the problem with one cable, you need to have the following pin-layout to connect a modem (HP has no such cable).

RJ-45 DB-25
(10-pin) (25-pin)
