It doesnt work the way you think it works, its not just some serial port that spits ASCII characters, rather I believe it requires you to speak IPMI to it. Of course, if you happen to have an IBM Bladecenter, then it does just look like a serial port on the blade, but you still have to deal with the management controller stuff on the incoming side. After you deal with all this stuff for a while you will LONG for the good old days of a simple UART :) Cheers, Jack
