@SKTL - Socket Listen Improved SELINT 0 / 1
When the connection is established the CONNECT indication is given and
the modem goes into data transfer mode.
On connection close or when context is closed with #GPRS=0 the socket is
closed and no listen is anymore active.
If the context is closed by the network while in listening, the socket is
closed, no listen is anymore active and an unsolicited code is reported:
@SKTL: ABORTED
Note: if all parameters are omitted the command returns the current socket
listening status and the last settings of parameters <socket type>, <input
port> and <closure type>, in the format:
@SKTL: <status>,<socket type>,<input port>,<closure type>
Where
<status> - socket listening status
0 - socket not listening
1 - socket listening
AT@SKTL? Read command has the same effect as Execution command when
parameters are omitted.
AT@SKTL=? Test command returns the allowed values for parameters <mode>, <socket
type>, <input port> and <closure type>.
