You also need a bit more magic.  There should be good documentation
someplace, but I don't know where it is.  Try man ldattach


I'm using this in /etc/sysconfig/ntpd on Fedora

if [ ! -e /dev/gps12 ]; then  # GPS 18x LVC
  ln -s /dev/ttyS0 /dev/gps12
  setserial /dev/ttyS0 low_latency
  ldattach 18 /dev/gps12
  ln -s /dev/pps0 /dev/gpspps12
fi
