I ordered several of the DB9-M to RJ45 adapters from Graybar Electric. Using my multitester, I determined that proper pin-out configuration to allow these adapters to work with a standard Cisco patch cable. I was able to take the special Alteon serial cable out of my laptop bag and replace it with an adatper that looks similar to the Cisco DB9-F console adaptr.
