Well,I just knew the refclock_nmea driver and it uses two device files:

With the patch or using the latest ntpd it should use /dev/gps0 for the
NMEA data stream and /dev/gpspps0 to tap into the pps signal.

If the drievr you want to use has the same original setup (data and
pulse on one serial port) it can be changed for the LinuxPPS approach as
was done in the NMEA refclock.

Kind regards,
