Has anyone successfully used the Ubicom sample dual UART & IIC multimaster
virtual peripheral ?

I've just returned to a project where I'm intending to use this code.
The dual UART had a fatal flaw which I have fixed. This probably came from
someone having duplicated code for a single UART but missing a common flag
fatally shared between the two routines - possibly OK if only one was active
at once and you changed serial connections over to test each in turn. I've
added a 3rd UART to this and they all work OK.

I've just started on the IIC (where I only need a single master) and at
first try it appeared "dead in the water".
I added a debugging call to a print routine part way through the code. This
needed a bank switch and I then restored the bank to where it "should" have
been after the serial call, and lo & behold, it burst into somethinfg like
life. Removing the serial call but keeping the subsequent bank call (which
should now be redundant) and it still works partially. This suggests the
basic code is flawed. If anyone else has used this with success I'd love to
hear from them. I'll no doubt get it going but short circuiting having to
fix something which isn't meant to be broken would be nice.

I'd like to think that it was just something I was doing wrong but the fact
that the UART was definitely broken suggests the other problem also may be
real.
