Yes, but that won't handle multiple volumes (which is a pain).

We have found that afio (after Les's post) will do the job.  It's not
perfect, but it does work.

Actually ISC hasn't been bad on the response lately.  My prior experience
with them was not nearly as fulfilling.  It appears that they are paying
more attention to the customer's needs these days (our last experience with
them was 6-8 months back).

Now if they could just get a proper terminfo entry in their distribution :-)
