Mport is a nice package, but I would not call the serial support good
without relating that there are problems using the ports at high speed.
We have seen repeated "double panic" messages when running the ports
to a Vax at 9600 baud. Mport suggested slowing the ports down as a fix.
However, it will be fixed in a future release. All this on real IBM hardware,
so it's not a compatibility problem.
