I just installed a 2 port serial adapter in my Ubuntu 10.10 system, then I tried following this tutorial that I used on my old system to connect to a cisco router (my old system had an onboard serial adapter, and the tutorial worked just fine). I can't get my system to connect to the cisco router, so I'm wondering if the card even works in Ubuntu. How can I tell if the card actually works with Ubuntu?
