    To keep the modem from answering the phone Add S0=0 to your init string.

    Speaker Control Init Strings

    M0 Speaker always off
    M1 Speaker on during connection
    M2 Speaker always on (very noisy)
    L0 Lowest volume
    L1 Lowest volume (redundant)
    L2 Medium volume
    L3 Maximum volume

    Making the Modem report the true connect speed
    For Rockwell-based 28.8 and K56flex units, the command to show your true connect speed is W2. (For Rockwell-based PCI modems, the command is MR=2.) The S95 commands and the &Q commands can override W2, so add S95=0 or S95=1.

    K56Flex - Is the Rockwell Based 56k Standard.
    X2 - Is the US Robotics Based 56k Standard.
    V.90 - Is the ITU recognized 56k Standard (sort of a combination of X2 and K56Flex).
