You usually should not have to fiddle with that, as the daemon code sets up the tty interface. The parity message refers to a parity error in the transmitted time code not in the characters received (each character is just a single bit the the time code). >> > This has nothing to do with parity check on the serial port. > > The DCF77 signal transmits 3 parity bits in its data stream. > This messages is generated when the check fails.
