I honestly accept I've never given it a thought. I was just floating with the crowd in the first half of my response to Pramod's question.
Anyway, what I feel is, all the second bits of the bit-stream being sent would be collected (assuming that a serial ISR is taking care of the incomming bytes). Because, the Serial port reads the incomming data (bit) at the falling pulse of the clock, it should, most probably be the second bit of every pair (that arrives in the clock period of the serial port).

Im eagerly waiting for the correct answer (if I am wrong).

Warm Regards,
