     It may be part of the POSIX standard, but there's nothing in the
     POSIX definition of tput that provides for cursor positioning or
     font attributes. The only defined operands are clear, init and
     reset.

     In fact, my scripts are portable to other terminal types by use
     of files for each terminal, generated with tput. Using a
     different terminal is as easy as ". /usr/share/term-sh/$TERM" or
     something similar. I generated a lot of files a few years ago,
     but I have never had any call for them, so I'd have to hunt for
     them.
