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).

OK
Host 1 accepts the Socket connection request:
at^siso=0 Host 1 accepts the connection request, where 0 is the ID of the
dynamically assigned service profile.
OK
^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.
at^siso? Query the current status of services.
^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.

OK
Host 1 rejects the Socket connection request:
at^sisc=0 Host 1 rejects the connection request, where 0 is the ID of the
dynamically assigned service profile.
OK
at^siso? Query the current status of services.
^SISO: 0, “” The dynamically assigned service profile is free again. The Socket
listener stays at <srvState>=3 (listening) and <socketState>=3
(LISTENER).
