[so2] SO2 labs

[Vlad Dogaru]

The interrupts are not bridged per se, rather the two serial ports are
connected to each other, aka loopback.  This is done in the VM
configuration, by pointing each serial port to a pipe and then linking
the pipes to each other.  See lines 7 and 37-44 of the Makefile used
to start the VM:

Hope this helps,
Vlad

It seems that the interrupts are bridged between the IO ports ranges of com1 and com2, but I can't seem to find where the bridging occurs.
