Parameter Description
<srvProfileId>
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
<srvParmTag>
, 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
<srvState>
=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
<srvState>
=3 (listening) and
<socketState>
=3 (LISTENER),
while the
<srvState>
and
<socketState>
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
<srvState>
"2".
Socket state identifier.
1
Socket not assigned, i.e. no TCP/UDP connection active.
2
Socket assigned as CLIENT.
3
Socket assigned as LISTENER.
4
Socket assigned as SERVER.
Number of bytes received via
AT^SISR
since last successful
AT^SISO
write command.
Number of bytes sent via
AT^SISW
since last successful
AT^SISO
write command.

Remote IP address in dotted-four-byte format or evaluated DNS name and TCP port, separated by colon, e.g.
