3. New Features:
========================================================
  3.1 Support call forwarding and new interrogation function for UK, these
      relatived AT commands and S-registers are described below:

      (a)Relatived AT commands:
         ATCFxy(forwarded number): Activate call forwarding
         where
             x = U : call forwarding unconditional(CFU)
             x = B : call forwarding busy(CFB)
             x = NR : call forwarding no-reply(CFNR)
         where
             y = A : Phone A
             y = B : Phone B
             y = I : Data call
             y = S : All services

         ATCFxy: Deactivate call forwarding

      (b)Relatived S-registers:
         S118, S109 and S111 are relatived with call forwarding basic services.
         These relatived meaning are explained below:

         (1)S118.4=0, don't care S109 and S111 : Using 3.1K Audio basic servies

            S118.5=1 and S111=1 : Using 3.1K Telephony basic servies for Phone A

      (c)Add interrogation function AT commands:
         (1)ATCFA? : For Phone A interrogation
         (2)ATCFB? : For Phone B interrogation
         (3)ATCFI? : For Data call interrogation

  3.2 Support call deflection function for UK, these relatived AT commands and
      S-registers are described below:
      (a)Relatived AT commands:
         ATCFDz(forwarded number): Activate call deflection
         where
             z = A : Phone A
             z = B : Phone B
             z = I : Data call

      (b)Relatived S-registers:
         These S-registers of call deflection basic services are the same as
         call forwarding basic services.

  3.3 Add call forwarding All services AT commands for UK, these relatived
      commands are explained below:

      ATCFxSy(forwarded number): Activate call forwarding All services
      where
          x = U : call forwarding unconditional(CFU)
          x = B : call forwarding busy(CFB)
          x = NR : call forwarding no-reply(CFNR)
      where
          y = A : Phone A
