        ********  Release Note for Version 4.01  *************

 1. Problem Fixed :

        a. Improve the performance on the lines with strong listener echo.

 2. Function Updated

        a. Expand the number of S-register to 50 (S0-S49). The modem
                will load factory default at the first power on. Please
                record your own current profile to avoid loss of your
                settings. After that, the modem will work as normal.

        b. Add the feature to disable throughput average (Bit 0 of S40).
                In default, the modem will average the thruput output to the
                DTE to avoid the burst data flow.
                If you set this bit, the modem will not average the thruput
                and transmit data to DTE without any delay.

                !!! Warning : It is not recommended to set the bit 0 of S40
                                if your PC is not fast enough or without
                                16550.
