I just referrred to that way as a short-hand way of describing it's
appearance instead of the code used to select it.
In all the software I've ever used, and on findu, and in the updated symbol
sets I have distributed up to the current "Rev H" that are derived from the
US customary symbol set originated by K4HG, the primary set "ampersand
code" yields a black diamond (i.e. square rotated 45 degrees) with a yellow
letter "G" on it -- not as an overlay code but part of the base artwork of
the symbol.
I don't think anyone is using a secondary code plus overlay character to do
this for an HF gateway. At least, none that I have seen. Indeed I have
seen the opposite a number of times on VHF in my travels. People are using
the primary /& "diamond-G" symbol to identify a two-meter igate.
Anything that depends on overlaid symbols from the secondary set will
simply not show on many users displays since many of the clients just don't
support the secondary overlay technique at all, or have
out-of-date/incomplete symbol sets, or both.

For $20 more you can get that same chip AND a GPS:
http://www.geeks.com/details.asp?invtid=UT-41&cat=GPS
(also I have found geeks.com to have far superior customer service compared
to tigerdirect)
I have 3 of these and I have had one on my desktop PC in a window for
several months.
I also disassembled one and found the TTL serial level data (but not the
1PPM pulse it should have somewhere). It does not work over 60k' according
to the specs. See the list archives for more detailed info from a few
months back.

Many of Deluo's devices (GPSes, etc) use the PL2303 too. That's nice if I
wanted an inexpensive GPS though.
I'm not the kind of person that wants to hack up something like that. I
needed a serial adapter for my Cisco routers, switches, and firewalls, as
well as for my TNCs (D700 and the DR135TP).
As for Tiger Direct, I buy from them pretty often, but only things that are
in stock and preferably not a deal logged on Techbargains, etc.

There's many people who have the same thing, however.

Bob,
My HP-Compaq NX-5000 has both a 9 pin serial and 25-pin parallel port - I
purchased it around 18 months ago. It's not an expensive or particularly
rugged unit but it does what I need...
I believe that at least some of the current NX-series still have serial ports.
