OpenBSD have 256 color support in xterm, which is xterm-256color. For console, setting the TERM to wsvt25 is better. Color will work but weird stuff will happen is you use xterm term type for console, such as funny scrolling while ls-ing, tmux behaving weirdly and other stuff. But is I use wsvt25 as my term type, mp3blaster won't work correctly, vim color scheme (I use wombat scheme) will display white background instead of the dark background. So, I have to set my .profile to detect the original term type and change it to the color version.
In console, the original term type is vt220, so I'll use wsvt25 for color but mp3blaster won't work correctly. In X, the term is xterm so I'll use xterm-256color instead.
I open up .profile and put the lines below.
# This is to check the TERM and change accordingly.
if [[ $TERM = xterm ]];
then export TERM="xterm-256color";
Then my console and xterm will have appropriate color enabled. Later then.
