The asynchronous packet in RS232 transmission

The diagram isn't helpfully large but here's a text-type link

Here's a Wikipedia link from which comes the diagram at left.










Note that this one has:

* a start bit
* 8-bit data transmission (limited ASCII may use only 7 bits)
* a single ( the usual) stop bit

* no parity bit (parity can be even or odd).
