These settings let you configure the serial connection parameters.
Note
You can only modify these settings before connecting to the serial port. If the fields are greyed out, Disconnect from port first.
| Setting | Description | Available Options |
|---|---|---|
| Baud rate | The speed at which data is transmitted between devices. Higher baud rates allow for faster data transfer but might be more prone to errors due to signal distortion. For information on supported baud rates, check the device's hardware user guide. The most commonly used baud rates are 115 200, 38 400, 19 200, and 9 600. | 50 to 1 000 000 |
| Data bits | The number of bits that carry data. | 8 (default), 7 |
| Stop bits | The number of stop bits. | 1 (default), 2 |
| Parity | An error-checking mechanism to detect errors in the data transmission. For example, even parity means that the number of 1s in the data byte and parity bit combined is even, while odd parity means that the number of 1s is odd. | none (default), even, odd, mark (Windows only), space (Windows only) |
| rts/cts | Request to Send (RTS) and Clear to Send (CTS) use two cross-coupled wires between the devices. If hardware flow control is enabled, each end will use its RTS to indicate that it is ready to send new data and read its CTS to see if it is allowed to send data to the other end. | off (default), on |
| xOn | When using software flow control, xOn (transmission on) signals that the device is ready to accept data. | off (default), on |
| xOff | When using software flow control, xOff (transmission off) signals that the device is unable to accept more data. | off (default), on |
| xAny | Software flow control setting. | off (default), on |
