lngarm.csv lookes lile this
70.6799,38.9870
70.7299,38.9870
70.7799,38.9870

You already have it, just remove -Sc which draws circles instead of connecting the dots.

If you want to show the points as symbols and plot the lines, then you call psxy twice. -L is for turning a line into a closed polygon.
