0.0.187:4100",0
OK
AT^SISO=0
The host opens service profile 0.
OK
Note: URC ^SISW:0,1 does not appear! The host
must poll the service state by means of AT^SISI until
the service is in <srvState> "Up".
AT^SISI=0
^SISI: 0,3,0,0,0,0
The service is still in <srvState> "Connecting".
OK
AT^SISI=0
^SISI: 0,4,0,0,0,0
The service is now in <srvState> "Up" and is
ready to accept data.
OK
AT^SISW=0,10
The host requests to write 10 bytes.
^SISW: 0,10,10

The host requests to write next 10 bytes and enables
the <eodFlag>.
^SISW: 0,0,10
But the service refuses the request, even the end-of-
data flag remains without effect.
OK
AT^SISW=0,10,1
Next try (polling).
^SISW: 0,10,20
Response that the service accepts 10 bytes and this
data and the previously sent data are unacknowl-
edged.

Polling for <srvState> change ("Closing" ->
"Down").
^SISI: 0,5,0,20,10,10
