++--------------------------------------------------------------------+
+
+  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.
