This is the most common + parity setting. Error detection is handled by the + communication protocol. + \value EvenParity The number of 1 bits in each character, including + the parity bit, is always even. + \value OddParity The number of 1 bits in each character, including + the parity bit, is always odd. It ensures that at + least one state transition occurs in each character. + \value SpaceParity Space parity. The parity bit is sent in the space + signal condition.

It does not + provide error detection information. \value UnknownParity Unknown parity. \sa QSerialPort::parity |
