I don't understand all this, but fyi I believe I have two "serial ports"
on the motherboard, one old fashioned serial-port and one created by BMC
for "SOL". They show up in dom0 as ttyS0 and ttyS1. Only ttyS0 is ever
used that I am aware of. I also have one usb-rs232 emulation thingy
which is actually my UPS. All of these are used directly by dom0.
