+--------------------------------------------------------------------+

  PURPOSE : This is the functional counterpart to the H AT command
            which is responsible to terminate or modify a call.

            1. The function searches for an active call. If this
            call is modifiable, it will be modified and the function
            returns.
            2. Then the function searches for a call that is in the
            disconnect request state and indicates CCBS possibility,
            this call will be finally released.
            3. If enabled the next search looks for a pending SAT call.
            If such a call is found the call is rejected and the SIM card
            will be informed.
            4. The next step is to clear all calls of the call table
            exept a waiting call. The function returns if at least one
            call could be found.
            5. If no call was found, the function searches for a waiting
            call. If a waiting call was found, the call will be
            terminated declaring the user as busy.
            6. If none of the above situations match, the function
            returns with a fail.
