#SCFGEXT (for the specific <connId>), then, when a TCP connection
request comes on the input port, if the sender is not filtered by
internal firewall (see #FRWL), an URC is received:
+SRING : <connId>
Afterwards we can use #SA to accept the connection or #SH to
refuse it.
If the ListenAutoRsp flag has been set, then, when a TCP
connection request comes on the input port, if the sender is not
filtered by the internal firewall (see #FRWL), the connection is
automatically accepted: the CONNECT indication is given and the
modem goes into online data mode.
If the socket is closed by the network the following URC is
received:
#SKTL: ABORTED
