Again, it fails even if W and N are omitted:

echo "66.5|44.25" | v.in.ascii -n output=DMS_test format=standard --o

Error reading ascii file:

I tried reversing Long and Lat, but get the same error. Interestingly, the
"Error reading ascii file" line disappears if I run the same command without
the -n flag, but still fails:

echo "66.5|44.25" | v.in.ascii output=DMS_test format=standard --o

Hi,

I think that decimal degree go without W and N since
the minus is used for West/South.

The above command also fails if the coodinates are given to 6 decimals
places, which probably doesn't even matter.

format=standard wants

L n
x1 y1 [z1]
..
xN yN [zN]

so " " not "|" and you need to start with the "L n" line.
