Hi, I am using the Java Communications API to connect to the modem (PCTel HSP56 Micromodem). Through the AT Command set I have successfully dialed a telephone. Now I need to play an audio message on the telephone. How is this possible ? I have heard that the basic AT Command set is same for all Modems. Is this true ? I would be grateful if anybody could send me sample code for this or point me to some tutorial.
