I put these lines in /etc/udev/rules.d/10-pps.rules:

KERNEL=="ttyS0", RUN+="/bin/setserial -v %k low_latency hardpps"
KERNEL=="ttyS0",                SYMLINK+="gps0"
KERNEL=="pps0",                 SYMLINK+="gpspps0"

At least they do not give me syntax errors when I do udevtest /dev/ttyS0
or udevtest /dev/pps0. (just that the device could not be opened)

But udevtest /sys/class/pps/pps0 gives me:

# udevtest /sys/class/pps/pps0
This program is for debugging only, it does not run any program,
specified by a RUN key. It may show incorrect results, because
some values may be different, or not available at a simulation run.

Is this OK? (I am not100% sure)

And:

# udevtest /sys/class/tty/ttyS0

Good?
