Hi Frank, thank you for your help!
It is not clear to me whether parity check shall be enabled or disabled! With stty -a /dev/refclock-0 I have the following output: [EMAIL PROTECTED] /]91# stty -a -F /dev/refclock-0 speed 50 baud; rows 0; columns 0; intr = <undef>; quit = <undef>; erase = <undef>; kill = <undef>; eof = <undef>; eol = <undef>; eol2 = <undef>; start = <undef>; stop = <undef>; susp = <undef>; rprnt = <undef>; werase = <undef>; lnext = <undef>; flush = <undef>; min = 1; time = 0; -parenb -parodd cs8 -hupcl -cstopb cread clocal -crtscts -ignbrk -brkint -ignpar -parmrk -inpck -istrip -inlcr -igncr -icrnl -ixon -ixoff -iuclc -ixany -imaxbel -opost -olcuc -ocrnl -onlcr -onocr -onlret -ofill -ofdel nl0 cr0 tab0 bs0 vt0 ff0 -isig -icanon -iexten -echo -echoe -echok -echonl -noflsh -xcase -tostop -echoprt -echoctl -echoke Is this a correct setting for the serial port?

The DCF77 signal transmits 3 parity bits in its data stream. This messages is generated when the check fails. This happens usually when the reception is sub-optimal and bit errors occur. Occasional errors are harmless. If this message is interfering with the opration of your embedded system you should only disable the output of the message - not the check.
