Some years ago, I remember reading an ad for a product that provided a low speed data link simultaneously with a telephone voice circuit. Now (of course) I need the info and its nowhere to be found. The product looked like an ordinary modem, and connected between a telephone set and a phone line. When a voice call was established between two of these setups, the modems carved out a chunk of the voice bandpass and used it to pass data, at (as I remember) about 300 baud. At the same time, a voice conversation could allegedly take place, with the missing bandpass not degrading the quality that significantly. Of course, the 'standard' used was completely proprietary; the modems could talk only to each other. Since this was before Hayes compatibility was universal, they probably weren't even compatible in that way. I don't know if that particular company is still around, or if someone else nowadays has a similar product. Does anyone out there know of such a product being sold today??
