Mark, Most sound card on a PC can to DTMF detection. Do you need RS232? JL
-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]]On Behalf Of Mark Sent: Thursday, November 22, 2001 7:12 AM To: [EMAIL PROTECTED] Subject: KX-T: DTMF detection for a pc I know this is slightly off-topic but it is a modification for my Pan1232 to allow it do some additional tricks. Does anyone know if a product exists which plugs into a phone line and can then send RS232 to a computer whenever it hears DTMF on the line? I need to find a way for a PC to handle someone entering a string of DTMF digits in order to check the number against a little database. If the number is valid, a relay will close and the call will then be connected to a pre-recorded message. (The line will be answered by a TAM). I would rather not build a DTMF decoder from scratch (I need to make four units in total), but I know that I *could* use a dtmf decoder IC and have it sent its data through to the keyboard. I'm just hoping that a gadget already exists so I do not have to re-invent the wheel.
