Today I successfully tested IPMI 2.0 card integrated within SuperMicro server. For server side, I've got /dev/ttyu0 as first physical port, /dev/ttyu1 as second and /dev/ttyu2 for SOL port automatically at boot time. Open request for /dev/ttyu2 locks waiting for DCD until I use ipmitool shell at remote workstation and command 'sol activate' in the shell. It gave me clean serial channel and I've successfully got getty login prompt, logged in, run Midnight Commander (TERM=xterm) without a problem. Eugene Grosbein
