That is why I suspect that it cannot run 50 baud.
What happens when you try stty 50 /dev/tty...?
[root@alarm dev]# stty 50 /dev/ttyAPP0
[root@alarm dev]# stty /dev/ttyAPP0

Normally with speeds below 300 (150, 110, 75, 50) bps both interfaces

Hello,
I wanto to keep the system clock of my embedded Linux board (Olinuxino
Maxi, based on iMX233) up to date using the DCF77 signal.
To do so, I wired the receiver to the RX line of the UART port and
symlinked it to /dev/refclock-1.
The receiver works well and delivers a good signal. I

It works fine for me.
I tried that and I still get the same errors. Then I rewired my receiver
to send out *noninverted* signals. Now I get:

Can the serial port run at 50 baud? This is a requirement for this
method of dcf parsing. Maybe the length of the divider register is
insufficient to go that low.
Maybe. I could ask the vendor about that.
The interesting thing is, that the error message
