A warning will be issued in the following cases:
If “pNumber” > 0 and a specific message to be retrieved from / deleted
on the server is longer than “pLength”.
If “pNumber” = 0 and all messages to be retrieved from / deleted on the
server are longer than “pLength”.
No warning will be issued in the following cases:
If there are no messages at all on the server.
If the server has message(s) below and above the “pLength” specified.
In this case, the message(s) within the range of “pLength” can be
successfully retrieved or deleted, but the message(s) above “pLength”
remain on the server without any further notification given to the user.
Therefore, after retrieving / deleting messages, it is recommended to
check the message status on the server. This can be done by adding a
further POP3 service profile using the POP3 user command List “2”.
pDelFlag Flag to be used with the POP3 user command Retrieve (“3”). Specifies whether or
not to delete retrieved emails on the server (optional).
For supported values of <srvParmValue> refer to <srvParmValuepDelFlag>.
tcpMR Parameter can be used to overwrite the global AT^SCFG parameter
"Tcp/MaxRetransmissions" <tcpMr> for a specific Internet Service connection
profile. If the parameter is not specified the value specified with AT^SCFG will be
used.
Supported values <srvParmValue> for this parameter are the same as described
for <tcpMr>.
Setting is not relevant for Internet Service "Socket" with type "UDP".
tcpOT Parameter can be used to overwrite the global AT^SCFG parameter
"Tcp/OverallTimeout" <tcpOt> for a specific Internet Service connection profile. If
the parameter is not specified the value specified with AT^SCFG will be used.
Supported values <srvParmValue> for this parameter are the same as described
for <tcpOt>.
Setting is not relevant for Internet Service "Socket" with type "UDP".
<srvParmValue>
Parameter value; type and supported content depend on related <srvParmTag>.
<srvParmValue-servType>
Supported Internet service type values in <srvParmValue> for <srvParmTag> value “srvType”.
Before changing the “srvType” of an existing service profile be sure that the profile is closed. To verify the
connection state of the service profile enter the read command AT^SISO. Only when <srvState>=2 is returned
for this specific service profile you can change its server type.
“Socket“ The Multi-Tech wireless modem acting as client or server (listener) for TCP, or as
client for UDP. If the wireless modem is TCP listener, at least two service profiles
are required. The first socket profile must be configured as listener. The second
service profile will be dynamically assigned when a socket connection request from
a remote client is incoming.
For this purpose, one service profile must be left free (= not configured with
AT^SISS). An incoming socket connection request will be indicated by the ”^SIS”
URC, with the next free <srvProfileId> shown inside the URC as parameter
<urcInfoId>. The connection request can be accepted or rejected by using
AT^SISO or AT^SISC and the ID retrieved from the “^SIS”.
“FTP“ EDGE device acting as FTP client.
“HTTP“ EDGE device acting as HTTP client.
“SMTP“ EDGE device acting as SMTP client.
“POP3“ EDGE device acting as POP3 client.
“none“ Reset Internet service profile settings. Operation is not allowed if profile is in use;
i.e., it was activated via AT^SISO.
<srvParmValue-alphabet>
Supported string parameter character set selections in <srvParmValue> for <srvParmTag> value “alphabet”.
“0“ Applicable character set is determined by current setting of AT+CSCS. Default (This is the
default value if the parameter is omitted (0 will be assumed).
“1“ International Reference Alphabet (IRA, seven bit ASCII).
