Until we know the comtrol drivers work 100% for all uses I'd be wary of
recommending them. Hopefully the new driver will do the trick. Cyclades
boards are rock solid and far better than 16550's because they help out
a lot (things like flow control are software driven on a 16550 which is
bad). The rocketports are very very fast and very efficient.
