This is a very easy technical question. That is, I will be happy with a confirmed yes or no. I want to write a program so that I can phone my computer from anywhere and enter key sequences on a touch-tone phone. Of course I want the computer to be able to recognize what keys are being pressed. I know that a modem will automajically answer the phone, but does it have the ability to recognize touch-tones after it answers? If the answer is yes then I am willing to take it from there, I just don't want to spend time trying to figure out how to do something that cannot be done. thanks in advance. Oh, if you wish you *could* give me a few hints as to how to do it. -- + Alan W.

Most modems will not be capable of this. I think I have een ads before for modems that also do "voice mail" (tone recognition, speech synthesis, sampling) but that was on a PC and was a specialized product. Your average modem has no circuitry for tone recognition. Alan> thanks in advance. Oh, if you wish you *could* give me a few Alan> hints as to how to do it. You could conceivably build the hardware for it; a tone recognition circuit isn't hard to build. You can even get a chip from Radio Shack which will do most of the work for you. Of course, then you have the problem of interfacing with the computer, both hardware and software, and you need to detect the phone ring to answer. All in all, not a simple hardware project perhaps, but not unrealistic. If there is already such hardware available commercially, I wouldn't be surprised, but I can't say where to look, as I don't know. Perhaps someone else can fill in the blank.

However, I saw a posting from someone else wanting to do this sort of thing. I think it was in sci.electronics or rec.dcom.telecom, but I can't find it now. Anyway, a company called TELTONE makes a device which plugs into a phone line, and has an RS232 port. As I remember, it could send and receive DTMF (touch-tone) signals as commanded by the RS232 port. I don't remember what other things it could do, but at the time it sounded pretty neat. It was just a few weeks ago that I saw it. Good luck. -hans ======================================================================== Hans-Gabriel Ridder Digital Equipment Corporation ridder@elvira.enet.dec.com Customer Support Center ...decwrl!elvira.enet!ridder Colorado Springs, CO

Of course I >want the computer to be able to recognize what keys are being pressed. I just got done talking to Mike Balch of TELTONE technical support. He read my previous followup to this posting, but is unable to post a followup, or send mail right now. He tracked me down and called me asking if I would post the information for him. I hope this isn't too commercial for anyone.... The device is called the T-130, sells for $369 (*ouch*). Mike is currently working on hooking one to his Amiga, and plans to interface a digitizer to do voice mail type stuff. I managed to track down the posting in comp.dcom.telecom, so since it explains the details pretty well, I hope no one will mind if I just include it. ****** Begin included stuff ****** Article 3930 of comp.dcom.telecom: Path: shodha.dec.com!shlump.nac.dec.com!decwrl!sun-barr!cs.utexas.edu!mailrus!accuvax.nwu.edu!nucsrl!telecom-request From: ssc-vax!clark@beaver.cs.washington.edu (Roger Clark Swann) Newsgroups: comp.dcom.telecom Subject: Telephone/Computer Interface Message-ID: <2601@accuvax.nwu.edu> Date: 4 Jan 90 05:55:27 GMT Sender: news@accuvax.nwu.edu Organization: Boeing Aerospace & Electronics, Seattle WA Lines: 26 Approved: Telecom@eecs.nwu.edu X-Submissions-To: telecom@eecs.nwu.edu X-Administrivia-To: telecom-request@eecs.nwu.edu X-Telecom-Digest: Volume 10, Issue 6, message 8 of 8 I seem to remember that someone was asking about an interface box here recently.
