Hello Glynn,

Hmm, I have two instances of "termios.h", one in /usr/include/termios.h 
and /usr/include/sys/termios.h, however I cannot locate a file with the 
name "termio.h" anywhere on my system.

I greatly appreciate the information, and better yet a fix!

The following 3 modules in addition to d.colors fails for the same 
reason:

   i.points
   i.points3
   i.vpoints


Please let me know when I may update the module(s) and give it a whirl.
