ENHANCED IP STACK AT COMMANDS
149 AT Commands for EV-DO-EV3 Modems
Notes
 For outgoing connections made with #SD the remote host is dynamically inserted into the ACCEPT chain for
the entire connection duration. Therefore the #FRWL command is used only for defining the #SL behavior,
deciding which hosts are allowed to connect to the local device.
 Rules are not saved in non-volatile memory. At startup the rules list is empty.
 Issue this command before establishing a data connection using the AT#SGACT command.
Example
To accept connections only from devices that are on the IP addresses ranging from 197.158.1.1 to
197.158.255.255, add the following chain to the firewall:
AT#FRWL=1,"197.158.1.1","255.255.0.0"
OK
Data Volume #GDATAVOL
Execution command reports, for the active PDP context, the amount of data received and transmitted by the last

Parameters and Values
<mode>
0 Resets the data counter for the all the available PDP contexts (1).
1 Reports the last data session counter for the set PDP contexts, in the format:
#GDATAVOL: <cid>,<tot>,<sent>,<received>
where:
<cid> - PDP context identifier.
<tot> - Number of bytes either received or transmitted in the last data session.
<sent> - Number of bytes transmitted in the last data.
<received> - Number of bytes received in the last data session.
2 Reports the total data counter, since last reset, for the all the set PDP contexts, in
the format:
#GDATAVOL: <cid>,<tot>,<sent>,<received>
where:
<cid> - PDP context identifier.
<tot> - Number of bytes either received or transmitted, in every data session
since last reset.
<sent> - Number of bytes transmitted, in every data session since last reset.
