'pic12 RS232 protocol code?'

Hi all,

I am building a home sunshade control system. Each sunshade is connected
to a RS485 bus sytem. At every sunshade there is a pic12c508 for it's
control.
I want to use a serial control protocol (1 start ; 8 data ; 1 stop)
using the pic12c508's internal RC oscillator.
Is this RC-oscillator stable enough for eg. 2400 baud communication?
(any code out there ?)
When it's not perhaps I could use a bittime measurement on the first
bit? (but how's this done?)

Thanks
