The bluetooth device in the h5xxx iPAQs is basically flawed. So
using the HWUART is not a complete solution to the problems found there.
But empirical evidence provided by past developers shows that the
hardware flow control provided by HWUART does improve the stability of
bluetooth usage.

So if the HWUART can be used, it should be. And since it is physically
wired to the same pins, there is little impact to the user.

Since this is still work in progress, I have no problem with accepting
it and making BTUART the default. But at some time the issue of
bluetooth stability will come up and it will have to addressed.
