#SKTL - Socket Listen
send escape sequence
+++
NO CARRIER
Now listen is not anymore active
to stop listening
AT#SKTL=0,0,1024, 255

The main difference between this command and
#SKTD
is that
#SKTL
does not
contact any peer, nor does any interaction with the GPRS context status, leaving it
ON

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.
