If it's only one line, then the simplest might be to re-write the ASCII 
file formated in the GRASS "standard" format, as a line. You'll need to 
add the header lines, something like:
VERTI:
L n 1
X_coord Y_coord
...
...
1 1

Where 'n' is the number of points.

Then run v.in.ascii ... format=standard and it should result in a line 
vector.
