Oh yea, on a KPC-3+ there's another way involving putting the GPS
into separate pins on the KPC-3+.  You then hook the computer only
to the TNC.  It does take special wiring for this.  You need to hook
the GPS into two pins on a DE-9 as I recall.  I'm sure somebody will
post a link to the hookup diagram.
