The method for recording audio data is the same, except that the command is AT+VRX, or AT#VRX, and the modem transmits audio data while the computer receives it. The RTS/CTS flow control are not used here (the computer must accept all the audio data it receives, and the modem automatically paces its transmission to match the audio sampling rate).
