<listenPort> Local listening port.

Notes
„
If successful, the command returns a final result code OK.
If the ListenAutoRsp flag is not set through the command AT#SCFGEXT (for the specific connId), then, when an
UDP connection request comes on the input port, if the sender is not filtered by internal firewall (see #FRWL),
a URC is received:
+SRING : <connId>
Afterwards, use #SA to accept the connection or #SH to refuse it.
If the ListenAutoRsp flag is set, then, when an UDP connection request comes on the input port, if the sender
is not filtered by the internal firewall (see command #FRWL), the connection is automatically accepted: the
CONNECT indication is given and the modem goes into online data mode.
If the network closes the socket the following URC is received:
#SLUDP: ABORTED
„
When closing the listening socket you do not need to specify the <listenPort> value.
