A little pkill might do wonders for you. I haven't used a T2000, but most of the time when I get "device busy" I have left a program running on the port. When I have a port actually "die" on me, it's usually a USB connected serial device, and the behavior is quite different. Either a physical disconnect or a reboot is needed, but that doesn't appear to be your situation. Nick.
How to unlock a serial port

Could it be that your non-auto-booting machine receives something that looks like input to the boot> prompt? Can you test with the serial cable detached? (It would be more comprehensible if it was the other way round: not booting with the supervising machine beeing *on* and by some strange mishaps sending input to the boot> prompt.) Marcus

For carp to work, I have it disabled on the virtual interface on the supervisor. I use ovirt so I do it on the network profile there. This is a libvirt filter option. Maybe it's applied by default on your setup. The idea is to disable this protection and allow mac spoofing. G
