Serial communications
Serial line settings used when the RPC is controlled through a serial port.
These settings must match the serial console or control-port settings configured on the RPC. Incorrect values can prevent probing and outlet control from working.
Properties
Serial baud rate
The baud rate to use to communicate with the RPC.
The baud rate is expressed in bits per second. It must match the RPC serial port configuration.

Data bits
The number of data bits in each character transmitted or received.
8 data bits is by far the most common setting, only choose 7 data bits if it is required by the connected device.

Stop bits
The number of bits signifying the end of data.
1 stop bit is most commonly used with 8 data bits, other options should only be chosen when the communicating equipment is known to required specific settings.

Parity
Parity checking is used to detect errors in the communication.
No parity checking is commonly used, only on specific use cases will another parity setting be required.
| Option | Label | Description |
|---|---|---|
none | None | |
even | Even | Even parity checking bits. The number of bits in each each transmission, including the parity bit, is even. |
odd | Odd | Odd parity checking bits. The number of bits in each each transmission, including the parity bit, is odd. |
