Parameter Description
0 ... 9 specified with
AT^SISS
.
Internet service state identifier.
""
Service profile is unused.
2 Service profile resources are allocated, i.e. at least the service type has been
set (parameter , value "srvType" of
AT^SISS
). The service is
not opened.
3 Connecting: State after opening a service with
AT^SISO
where the connection
is being established.
If connection setup is successful the service proceeds to the state "4" (Con-
nected) and one of the URCs "
^SISW
" and "
^SISR
" may follow. If connection
setup is not successful, the "
^SIS
" may appear.
In the case of SMTP, the service will not enter =3 until the host
has written the first data packet with
AT^SISW
.
If the service profile is configured as Socket listener then the listener always
stays at =3 (listening) and =3 (LISTENER),
while the and of the dynamically assigned ser-
vice profile may change. See examples in Section 10.3.1 .
4 Connected: Socket connection valid.
5 Closing: Socket connection releasing. The Closing state is reached after send-
ing the
AT^SISC
command or after a service has closed automatically, such
as FTP download or POP3. In the latter case, it is necessary to send the
AT^SISC
command even though the FTP download or POP3 service has
already entered "2".
