target gtm900 renamed to gtm900mgc2 This change reflects the fact that the build target in question supports MGC2GSMT hardware only, and will NOT work on other hw that confusing bears the same end user name of GTM900, neither the LoCosto-based GTM900-C nor the Calypso-based MG01GSMT that has a different and incompatible RFFE. If we ever get our hands on a piece of MG01GSMT hw and add support for it, that other target will be named gtm900mg01.

| PROJECT : GSM-PS (6147)         MODULE  : CMH_CCS                  |
| STATE   : code                  ROUTINE : sAT_H                    |
+--------------------------------------------------------------------+

  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.

            exept a waiting call. The function returns if at least one
            call could be found.
            2. 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.
            3. If none of the above situations match, the function
            returns with a fail.
