#SKTD - Socket Dial SELINT 0 / 1
0..65535 - port number
Note: <closure type> parameter is valid only for TCP socket type, for UDP
sockets shall be left unused.
Note: <local port> parameter is valid only for UDP socket type, for TCP
sockets shall be left unused.
Note: the resolution of the host name is done when opening the socket,
therefore if an invalid host name is given to the #SKTD command, then an
error message will be issued.
Note: the command to be successful requests that:
- the GPRS context 1 is correctly set with +CGDCONT
- the authentication parameters are set (#USERID, #PASSW) the GPRS
coverage is enough to permit a connection
- the GPRS 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
Note The main difference between this command and #SKTOP is that this
command does not interact with the GPRS context status, leaving it ON or
OFF according to the #GPRS setting, therefore when the connection made
with AT#SKTD is closed the context (and hence the local IP address) is
maintained.
#SKTD - Socket Dial
