- : Well, in Byte magazine March 1985, Steve Ciarcia describes how
- : to do this. It required a special modem chip and board which he

- : the followup article in the next month's issue which has all the
- : software. The modem chip he used was pretty high tech for the
- : time. It was an 8250 and hayes modem all on one chip. It could
- : send and detect touch-tone (tm) signals and one version of the
- : chip had a text to voice synthesizer. The board also had audio
- : in/out lines so you could record responses or play any audio
- : source to the incoming call. All in all, it was a cute project.

- : As for the why, I can think of several reasons: Automated polling
- : both dial-in and dial-out (obnoxious, please don't do this.) You
- : could use it as a call up information service. One of my
- : favorites is remote contol for electronics at home but that would
- : require a great deal of circuit building and programming.

- Thanks for the info. I'm setting up a system which will page an engineer when
- it wants him (or her). Current pager technology only permit a page to get
- through about 60-70% of the time. While high, this isn't good enough so the
- system will repeatedly attempt a page (pages fail because of metal content in
- the walls so if he moves...) until the engineer finds a phone and confirms
- receipt of the page (by dialing a code).
