16,-12 works for me when specifying a point for a line
About positive limits on the drawing:
If you can draw a line with the mouse on the negative area, then no, there are not positive limits in your drawing.

It would be interesting to know what exactly the error message is so somebody could search its text inside the sources.
Also what exactly did you to get that error, something in the style of "click on the line 2 points icon" then "click on the commandline widget" then "write 16,-12  and hit enter"
and maybe also the version of LibreCAD you use
HTH
