Note
The main difference between this command and
#SKTD
is that
#SKTL
does not
contact any peer, nor does any interaction with the CDMA context status, leaving it
ON
or
OFF
according to the
#CDMADC
setting, therefore when the connection
made with
#SKTL
is closed the context (and hence the local IP address) is
maintained.
