Sorry, I haven't read carefully on Patrick De Groote's reply, so forget two of my previous reply. Patrick's got the point, if you need to communicate in data mode, you have to use another modem at the other end (and watch for the not-often-used pins). However, if you want to use DTMF reply, use voice communication and a DTMF receiver like MT8870 to inform the microcontroller about the data sent by the telephone. |
