Hamish, thanks for your quick reply. If I have well understood the command usage, v.distance connects a point to the closest one irrespective of the category, and can not solve my problem. Actually I solved the problem transforming the point files to ascii files with v.out.ascii, pasting them, transforming in a ASCII file containing lines by gawk and importing with v.in.ascii. The resulting vector line is perfect. I posted the question because in GRASS there are very sophisticated modules to solve complex network problems and tools to connect lines (as in v.edit) and I thought very unlikely not to have a module to simply connect points. Probably such a module or tool is not so simple as I suppose.
