)HOST and popen are essentially the same thing and they both capture
output of the command you are running.  But as they take command to
be interpreted by shell, you can explicitly redirect output to the
terminal yourself:

      )HOST vim >/dev/tty

In case of vim, which reinitializes terminal settings itself and isn't
bothered by having echo disabled, this is everything you need to make
it work.
