#SKTD - Socket Dial
-
the EPS has been activated with
AT#GPRS=1
Note: If all parameters are omitted then the behaviour of Set command is the same
as Read command.
AT#SKTD?
Read command reports the socket dial parameters values, in the format:
AT#SKTD: <socket type>,<remote port>,<remote addr>,
<closure type>,<local port>
AT#SKTD=?
Test command returns the allowed values for the parameters.
Example
AT#SKTD=0,1024,"123.255.020.001",255
CONNECT
AT#SKTD=1,1024,"123.255.020.001", ,1025
CONNECT
In this way my local port 1025 is opened to the remote port 1024
AT#SKTD=0,1024,"www.telit.net", 255
CONNECT
