well because it isnt using IP, besides SOIP is uninspiring :)

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 :)
