This is driving me nuts, since it was working and now it isn't and I have no idea what has changed. I hope someone can help.

I have a SunFire V490 at work. I also have a HP ProLiant server in the same rack, which is running Ubuntu Server 10.04. I've got the weird cyan serial cable plugged in to the lone serial port on the ProLiant and the other end plugged into the V490 port ("SERIAL"). I've got minicom running on the Linux box configured for 9600, 8N1 on /dev/ttyS0. minicom's status line reports "OFFLINE", and I get no response to any keyboard input.

What's wrong? I can freely power off/on the SunFire and anything else I want to do with it. I have the keys for the front panel, too. Do I have to switch it to diagnostics mode or something? We had it working before, and it was quite easy.

Help!
