9 Maybe, but Cisco is known for having a "special" pinout.

11 Best bet is to get a build-it-yourself RJ45 to DB9F adaptor - about
12 US$2.90, and the associated pin pusher - cause you'll mess up a
13 few times.
14
15 you;ll need to figure out which pins are transmit and receive - 2, and 3 on the DB9
16 side. Also, note that different brands of RJ45 to DB9F connectors have
17 different color codes for the wires. Typically you'll use 5 of the 8 wires, so best to
18 create a map on paper. There is supposed to be the Yost standard, but certain
19 folks do violate it at times - Cisco, Dell, etc. So you need to know the RS232 pinout
20 of your system.
