Patrick, In an article (Volume 10, Issue 463, Message 3 of 8), you write (as a postscript): > [Moderator's Note: There are commercial devices available which allow > what you want, and also accept incoming calls to tell you about the > temperature at the place where the device is located, then allow you > to listen to background noise for thirty seconds or so. In the event > of some problem (usually a choice of three or four problems) they call > out to up to four(?) different phones, and keep calling until someone > presses certain tones on the phone to reset the device. PT] Could you please point me to a source for these devices? Bruce W. Mohler Systems Programmer (aka Staff Analyst) bruno@sdcc10.ucsd.edu voice: 619/586-2218 [Moderator's Note: The last time I saw one advertised (a week or so ago) it was in the Global Computer Supply mail order catalog. I wish I had it here now -- I tossed it out -- so I could quote you the page and other details. I think it can tell if there is water in the vicinity (because a probe gets wet; a contact is shorted, etc); if there is a fire (because the temperature gets very warm in the area); if there is a break-in (because output of burglar alarm device is fed to this unit), and more. These units are also used in cold storage warehouses to tell if the power went off, i.e. the temperature is above a certain point. When you call in, a synthesized voice says "the time is 12:34:56 7/8/90". The temperature is X degrees. Everything is normal. Now listen!" ... and the built in microphone lets you listen for familiar (and unfamiliar) noises in the room. They also call you when activated, and chant their message over and over until you shut them off. Try Global (they have an 800 number), or other computer peripheral supply houses. Maybe someone with their catalog or a similar one will write you with info. Please, someone? PT]
