Arduino UNO UART data frame

I am plalying with serial.print() functions (and the related function)

How do I identify what data frame is applied by the UART of UNO.

How many data bits per frame?
Parity even or odd or non?

How many stop bits?

I don't understand the question

How many data bits per frame?

8

Parity even or odd or non?

None

How many stop bits?

1

Thank you for the replying.

What I asked is about the parameters of the UART communication of Arduino.

Normally, the UART transceiving should be configured with proper data bits number, parity setpu, and stopbits number on both TX and RX side.

But if I directly call the serial functions, I didn't setup these at all. How do I change these parameters?

Useful reference

OK, I got it. Thank you very much.
