Serial to ethernet cable: how to connect to device
That cable is not a serial to Ethernet cable. It is a female DB-9 to 8P8C plug serial cable. Cisco uses 8P8C connectors that are the same as copper Ethernet for console access to their equipment. That cable would normally go from 9pin serial on your computer to the router console which is also serial. I'm guessing since you thought it was serial to Ethernet your HP kit has a male 9pin connector on it? If so you will need a 9pin null modem cable with female 9pin connectors on both ends.

How can I use a serial to ethernet cable to connect to a device: in my case a Hp ProCurve AP?
A serial to USB or serial to serial would have been great but I found this serial to ethernet cable from a Cisco router lying around and I though that I might use it.
Is it possible?

Dragos over 12 yearsThanks Thomas. You are right, I looked carefully and its a 8P8C serial not ethernet.

Thomas G over 12 yearsMost USB -> Serial adapters will be male on the DB9 connector since they are designed to present a DTE signal to a DCE device (modem, etc). It is most likely if your AP has a male DB9 it is also DTE in which case you need an adapter or cable that reverses Tx and Rx pins as "null modem"
