| 1. | The start bit signals the receiver that a new character is coming.
|
| 2. | The stop bits gave the system time to recover before the next start bit.
|
| 3. | The stop bits are marking, so as to be distinct from the subsequent start bit.
|
| 4. | The data frame contains 10 bits : 1 start bit, 8 data bits, 1 stop bit.
|
| 5. | Such a machine would send 1 start bit, 5 data bits, and 1.42 stop bits.
|
| 6. | Each byte is transmitted in the sequence " 1 start bit-8 data bits-2 stop bits ".
|
| 7. | After the start bit and before the eight data bits is another pause of at least 1 / 1800 seconds.
|
| 8. | The link is based on character asynchronous transmission with 1 start bit and 1, 1.5 or 2 stop bits.
|
| 9. | The receiver tests the state of the incoming signal on each clock pulse, looking for the beginning of the start bit.
|
| 10. | The preamble should send V-Hi for three periods then V _ Low for one period then a logic 1 start bit.
