That looks like a perfectly normal GPS data string. You're lucky it's
not some wierd proprietary binary format! You should be able to feed it
into a serial port separate from the one your TNC is using, and then set
UIview to use the port under "Setup, GPS Setup". I.E you will require
TWO serial ports (or USB-to-serial "dongles") on your PC -- one for the
TNC and one for the GPS.
Not sure which GPS "sentences" UI-View actually requires. Can you
enable $GPRMC and $GPGLL as well? (These two sentences are required to
get speed and altitude into an APRS posit.)
