4.      Notes:

        V.120 under CAPI 2.0 and CFOS (version newer than 07/15/96):

        Enter the following AT-command:

            AT B12 S17=1 S76=1

        Now, the ISDN adapter board tries to get a V.120 connection
        erverytime you dial "ATDn" (n = number)..

        If you want to get back to X.75 mode, you have to enter:

            AT&F

               - - - - - - - - - - - - - - - - - - - - - - - -

        Modemconnection under CAPI 2.0 and CFOS:

        Enter the following AT-command:

            AT B7

        Now, the ISDN adapter board tries to get an analog connection
        erverytime you dial "ATDn" (n = number)..

        For an automatically modemconnection acceptance you must enter
        the following AT-commands:

            AT &IA S44=1 S0=1


        If you want to get back to X.75 mode, you have to enter:

            AT&F

        To suppress screen messages call VCAPI20.EXE with "/Q".

        The VCAPI20 has only been tested with cFos (DOS) and
        T-Online (Windows 3.1).

        The Soundblaster 16 PnP is handled as non Plug and Play
        device when you use the original OS/2 Warp 4 driver. This
        may result in conflicting resources. You should use the
        actuel PnP driver.
        
        Even if Plug and Play is supported it is possible to have
        conflicting resources. This conflicts are caused by non Plug
        and Play devices for which no snooper is installed. To solve
        this conflicts you can manualy reconfigure these devices to
        unused resources.
