> 10.5.1 | Example: Accepting / Rejecting Socket Connection Request from Remote Client

> Host 1 configured as Socket listener with IP address 10.10.0.187 at port 65534 is receiving a connection request from the remote client 10.10.0.185 (at port 1024). The example assumes that connection and service profiles have been created as stated earlier.
> Start the Socket service in listener mode, then query the IP address dynamically assigned to the Socket listener:

> at^siso=4 | Host 1 opens the Socket service.
> at^siso? | Query the current status of all services. All service profiles are unused, except for service profile 4 which is running in listener mode, where <srvState>=3 (listening) and <socketState>=3 (LISTENER). The response also indicates the IP address dynamically assigned to the listener. The listener's access data (IP address and TCP port number) shall be passed on to the client.

> Indication of incoming Socket connection request:

> ^SIS: 4, 1, 0 | The URC indicates that the listener configured on service profile 4 is receiving a Socket connection request (<urcCause>=1) from the remote client. The last URC parameter <urcInfoId> represents the ID of the dynamically assigned service profile, here 0.

> ^SISO: 0, "Socket","2","4","0","0", "10.10.0.187:0","10.10.0.185:1024" | Indication on host 1 that the connection request from the remote client has been dynamically assigned to service profile 0 which is set to Server mode (<socketState>=4).

> ^SISW: 0, 1 | The URC indicates that data transmission to the remote client is possible. If the remote client has already sent some data the additional URC ^SISR: 0,1 is displayed.

> ^SISO: 0, "Socket","4","4","0","0", "10.10.0.187:65534","10.10.0.185:1024" | The socket connection between host 1 and remote client is successfully established.
