RCFAST and <> 80mhz options?

Hiya
The manual doesn't appear to be clear (or at least not to me, which probably isn't the same thing!).
I can run the propeller:
at 12mhz?· But my fullduplexserial doesn't work - even at 9600 baud.· Surely it can't be that slow / inacurate off the internal clock?
If I want to run with crystal for acuracy, then can I use the current 5mhz crystal and just change the PPL mode? i.e.
Or have I just answered my own questions?
I love this chip - is there anything it can't do?

_clkmode = RCFAST

_clkmode = xtal1 + pll1x ' 5mhz _clkmode = xtal1 + pll2x ' 10mhz ... _clkmode = xtal1 + pll16x ' 80mhz

I'll run it with the 5mhz crystal!
