... by default, anyway.  There is a command you can send to put it in a
sort of monitor mode so that you can see lots of data.  U think the NMEA
sentences pass through, but unfortunately the APRS data is in some odd
internal format and I've never tried to reverse engineer it so that it
could be translated into an APRS data stream.  Here are a few examples of
the specific strings that pop up when a station is heard:
