+
+PURPOSE : This is the functional counterpart to the +CGACT= AT
+          command which causes the cids specified in the cids list to
+          be activated or deactivated according to state.
+
+          An empty list will cause all defined contexts to be
+          activated or deactivated. If taken literally, this means that
+          if more contexts are defined than supported, each will be
+          activated, resulting in 'no resource' errors for the late ones
+          as the GACI SEM will reject requests for more activations
+          than it can cope with.
+
+          Note that the context is/are activated, but no CONNECT is sent
+          to the TE. This is the difference between ACT and DATA commands.
+
+          SMREG activate req does not need l2p to be sent, but in this case
+          the PDP config options are undefined (see below).
+
+          How does a DATA call bind these 'orphan' connections to a TE given
+          that a cid definition is a 'template' due to its ambiguity.
+
+          Practically, the activate form of this command has little meaning in the
+          case of PPP and loopback protocols (only ones supported at present).
+
+          Simplest option at the moment is not to support the activate form until
+          a protocol type is supported can make real use of it. The deactivate form
+          is of use in switching off a Loopback connection.
+
+          If activation before protocol establishment is supported, a NULL protocol service
+          will have to be provided which supplies a default (empty?) PCO list to SMREG for
+          activation and stores the network PCO response until a CGDATA is issued, must then
+          convert the protocol into that requested by the CGDATA command.
+          For future implementation
+
+
+          Other issues for multiple context activation :
+
+          - need to add a para onto GACI activate to tell it whether
+          to do a CONNECT or an OK callback on activation.
