        Mit den DIL-Schaltern S1..S4 koennen Sie die Adresse und den IRQ
        des ISDN-Bereichs Ihrer ISDN-Adapterkarte einstellen:

        Do the following steps:

        a) Start INSTALL.EXE from the OS/2-directory of your Driver-Media.

        b) Select your Protocol.

        c) Restart the computer by doing a Shut-Down.

4.      Notes:

        V.120 under CAPI 1.1 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

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

        To suppress screen messages call VCAPI11.EXE with "/Q".

        The VCAPI11 has only been tested with cFos (DOS) and
        T-Online (Windows 3.1).

        ELSA LocalWeb or on our homepage.

        Have fun with your ELSA ISDN board.
