... • RS-232-C uses a very simple mechanism: all communication starts with a ‘1' (known as a ‘start bit’- the idle state is a ‘0'). Per byte, 10 bits are transmitted. • Both Tx and Rx know the expected sampling speed (it must be arranged previously), hence the Rx can sample at the correct time. However ...

Before using the destination address in an intermediate or the destination node, the packet goes through error checking that may help the node find the corruption (with a high probability) and discard the packet. Normally the upper layer protocol will inform the source to resend the packet. 19-Match ...
