"dumb" terminal should not have a bell
When debugging something else, I've noticed that on Illumos, and as best as I can tell only Illumos, the "dumb" terminal appears to have a bel
tput -Tdumb bel | cat -v
This seems wrong (and different from every other system I can find).

I've checked other OSes, and only FreeBSD doesn't have bel defined for the 'dumb' terminal type, Solaris 11 and Debian/GNU Linux do have it defined. If you are really concerned about it, we could ask on ncurses mailing lists (as current terminfo/termcap sources come from it).
