@SKTL - Socket Listen Improved
SELINT 0 / 1
to stop listening
AT@SKTL=0,0,1024, 255
OK
Note
The main difference between this command and the #SKTD is that @SKTL
does not contact any peer, nor does any interaction with the GPRS context
status, leaving it ON or OFF according to the #GPRS setting, therefore
when the connection made with @SKTL is closed the context (and hence
the local IP address) is maintained.
