#DNS – Manual DNS Selection
<cid> - context identifier
1..5 - numeric parameter which specifies a particular PDP context definition
<primary> - manual primary DNS server, string type, in the format
“xxx.xxx.xxx.xxx” used for the specified cid; we’re using this value
instead of the primary DNS server come from the network (default is “0.0.0.0”)
<secondary> - manual secondary DNS server, string type, in the format
“xxx.xxx.xxx.xxx” used for the specified cid; we’re using
this value instead of the secondary DNS server come from
the network (default is “0.0.0.0”).
Note: if <primary> is ”0.0.0.0.0” and <secondary> is not “0.0.0.0”, then issuing
AT#DNS=… raises an error.
Note: if <primary> is ”0.0.0.0.0” we’re using the primary DNS server come from
the network as consequence of a context activation.
Note: if <primary> is not ”0.0.0.0” and <secondary> is “0.0.0.0”, then
we’re using only the manual primary DNS server.
Note: the context identified by <cid> has to be previously defined, elsewhere
issuing AT#DNS=… raises an error.
Note: the context identified by <cid> has to be not activated yet, elsewhere issuing
AT#DNS=… raises an error.
AT#DNS?
Read command returns the manual DNS servers set either for every defined PDP
context and for the single GSM context (only if defined), in the format:
[#DNS: <cid>,<primary>,<secondary>[<CR><LF>
#DNS: <cid>,<primary>,<secondary>]]
AT#DNS=?
Test command reports the supported range of values for the <cid>
parameter.only, in the format:
#DNS: (1-5),,
3.5.5.1.71. Socket TCP Connection Time-Out - #SKTCT
#SKTCT - Socket TCP Connection Time-Out
AT#SKTCT=
[<tout>]
Set command sets the TCP connection time-out for the first CONNECT answer
from the TCP peer to be received.
Parameter:
<tout> - TCP first CONNECT answer time-out in 100ms units
10..1200 - hundreds of ms (factory default value is 600).
Note: this time-out applies only to the time that the TCP stack waits for the
CONNECT answer to its connection request.
