Has anyone ever seen any of the graphics characters print in a madtty of dvtm? I don't think they work because they're not being displayed by an ncurses function, just by plain old write(), so there's no graphics translation being performed. Try echo'ing out this escape sequence and see what you get (remembering to replace '^[' with an actual ESC char):
echo "^[(0lqj^[(B" >From your regular terminal it should pring an ULCORNER+VLINE+LRCORNER. >From within dvtm it just prints l+q+j Anybody get different results or have ideas of how to fix? Thanks -Ross
