According to the manual, it has drives three devices:
NMEA 0180, 0182, 0183 vers 1.5 and 2.0.
Yes, it says three. I see nothing about PPS.

The PC plug is a nine pin female plug.

Do you have any documentation on what's on each pin?

Tell us the Garmin model number, Garmin has decent online documentation.

No. It's probably obtainable from Garmin. I'll check it out.

Only three are connected: 2 is receive data, 3 is transmit data, and
5 is ground. More?

I found it from someone and just posted it, but if there's more to it, I'll get the
model #. I'm looking at it right now and it says nothing but Garmin GPS 12XL, 12
channels.

OK. You should still look over Garmin's documentation very carefully,
but it looks like you don't have a PPS signal. (As someone else
mentioned, the model number would help.) I've seen postings to the
effect that you may experience too much jitter this way, but maybe it's
worth a shot.

Your model can output either NMEA or its own Garmin format.

After reading up on your 2 month travail -- googling by author revealed
alot you had not shared here before ;-) -- I looked at Garmin's site.

You will need the "sales" name for the unit, not its model # -- go
figure. Anyway, it's here:

http://www.garmin.com/support/download.jsp

All the ones I tried offered up User's Guides, spec sheets, etc.

As you mentioned, you still need to get XP's ntp working. I'll send
along the docs I've read tomorrow -- I suspected all along that besides
the registry edits you would have to play with the new firewall (WF --
Windows Firewall, catchy, huh?) and it has changed a _lot_. In fact,
one of MS's better efforts in a while. At least the docs are pretty
clear.

I'll also send along the link for the Critical Update for their new WF
-- affects dial-up routing table entries that effectively let _anyone_
through WF when the link is active ;(
till tomorrow (or is it today already?),

I thought so too till reading carefully today (and confirming on
cousin's XP box). It can and _does_ slew the clock but _only_ if it is
0+ to 3 minutes _fast_. Otherwise, it just steps the clock. But w32tm
command _can_ be used to to slew the clock _and_ discipline the
frequency "by hand". Strange ...

Simply not so since W2K. They just require registry edits to enable
the "server" role -- even the SNTP protocol doesn't really distinguish
clients from servers. It's the same software, just sometimes it asks
for the time and sometimes it gives out the time. And with SP2
(earlier?) XP implements NTP, not just the old W2K SNTP.

Especially if you're squimish about editinig the registry. Nothing
like maintaining 2500 Win3.1 to Win98 machines inadequately locked
down(able) to get you over _that_ hurdle ;-)
