programmable modems.

From:  W. J. Showalter <gamma at edn-unix>

I would like to find out what companies sell, for lack of the proper term,
programmable modems.  Specifically, I would like information regarding the
type which would permit access only from a specific phone by immediately
hanging up and them re-dialing the intended user.  Of course, any other
applicable models would also be of interest.

I realize that this question has nothing to do with Unix but there is a
plethora of knowledge on a wide variety of subjects within the wizard
community.  If there is a more appropriate mailing address for questions
of this type please let me know.  Send replies to gamma at edn-unix or to
unix-wizards as appropriate.  Thanks for your time.
