Caller*Id is an extra price option, available from your local telephone company, that provides the telephone number of the person calling you. The telephone number is delivered to a separate unit, the Caller*Id interface. This interface is available from several dealers (Sears, AT&T Phone Stores, etc), and must be purchased separately. The current model is the 125C, priced at about $60 from Sears. All the interface units (125, 125A, 125B and the current 125C) have the same drawback: they only display the telephone number of the caller, not the caller's name. That can make it difficult to "filter" people you don't want to talk to (like that annoying magazine subscription person). The circuit in CALLID.PNT provides a method of obtaining that information. Inside all of the Caller*Id interfaces is an XR2211 integrated circuit. This "chip" has as it's output the data stream containing the information sent over the telephone line (for you techies, it's a Bell 202 data stream, sent between the first and second ring). All that is necessary to connect the Caller*Id unit to your RS-232 port are: an MC1488 integrated circuit (available from Radio Shack, for about $l) and a resistor (lOOK Ohm 1/4 watt, also available from Radio Shack). The MC1488 "boosts" the output voltage to the level expected by the RS-232 port on your computer, and the resistor provides some isolation and reduces the voltage drop on the output of the MC1488. The MC1488 needs a +/- 12volt power supply. If you have one, you're all set. If not, Radio Shack sells small 9 volt power supplies for S5-6 each; you can put two back-to-back to get a +/- 9 volt supply, which is close enough. You could use a couple of 9volt batteries, too. Everything, excluding the power supplies, fits into the Caller*id interface case. I used a little hot-melt glue to place the MC1488 in an unused circuit board area (watch out for the plastic standoffs on the case!). Small gauge wire (or wire-wrap wire) connects the components together. If you're uncomfortable soldering to the integrated circuits, you can pick up IC jumper clips at Radio Shack as well (that way you can easily remove the "modification"). I bring the RS-232 pin 3 and pin 7 connections to a 1/8 inch mini-phone jack, which I mounted on the case near the existing telephone jacks. Once the circuit is built, what do you do with it? I use a Hypercard Stack built on the EXCELLENT Portfolio Hyper System (PHS), by Bob Davis 70625,717, to look up the phone number, announce the caller (using Macintalk) and provide filtering (based on time of day and flags on the caller's record). I log all incoming calls, both to a separate file and to the record of the caller. My stack also contains records for telephone exchanges, so if the specific number is not found, it will announce where (what town) the call is coming from. In addition, since I have two Macintosh computers, I broadcast the information over Appletalk, so both machines can announce the caller. That should give you enough ideas! Following is an extract of the major portion of the Hypercard script I use. I can't upload the entire stack, since it's part of PHS. It should give you enough of the logic needed to build your own application. By the way, all of this is PUBLIC DOMAIN, for NON-COMERCIAL USE. If you want to sell something with this, send me an EMAIL and we can discuss it.
