Parameters
----------

The port on which to listen.
listen_wait : int
Greater than zero if this method should wait for that many seconds for received packets.
If less than or equal to zero, this method will return a boolean type.
verbose : bool, optional
returnbytes : bool, optional
If True, returns bytes, instead of a string.
Returns
-------
s : bool
False if a packet data session was not active, or if setting up the UDP socket failed.
True if the modem successfully started listening for packets.
m : str or bytes
Any URCs that arrived while listening for packets.
