Clocks |
| Used to connect ports transmitting at |
| different baud rates. In order to | |
|
| |
|
| function, all ports must have and use |
|
| this feature. |
| Receive Control | |
|
| Receivers are always enabled. In a Half |
Always Receive |
| Duplex mode, you will receive what you |
|
| transmit (sometimes called echo). |
|
| Receivers are only enabled when not |

|
| you will not receive what you transmit. |
|
| Transmitters and receivers are always |
Full Duplex |
| enabled; ports can send and receive |
| simultaneously. Used in | |
|
| |

| communication. |
Half Duplex using RTS |
