I don't think the int osc is all that great for RS232 comms, but it can
work if you don't need super fast transfers.

I usually transfer like this..byte-ACK-byte-ACK-byte-etc

If you have long stop bits then the same result may be achieved.

I guess this minimses the chance of errors given the tolerance of the
oscillator.
