Last time I checked, several years ago, the simulator/trainer had a
'serial' config option which should allow the user to hook this onto
everything that is getting declared a being a serial interface by the
underlying OS.
Therefore, with a small to medium amount of fancywork it _should_ be
possible to route FlightGear's serial output into a serial interface in
Wine.

Cheers,
Martin.

It would be great if it was possible to drive the windows based 400-series
simulator software, but I don't have any idea if it's setup to respond to
serial input.  My understanding is that it had a graphics front end combined
with a backend engine that communicated via network packets.  But I could be
wrong.

Regards,

Curt.

Alas, I haven't yet figured out how to commit physical hardware to CVS ...
maybe with GIT?   I can commit the protocol updates soon though. :-)

This sounds great to me. Even though I would not count the GNS430/530
as being among my personal favourites, I know they are _very_ popular
and I've been using such thing at least in two different aircraft. If
I'm not mistaken, this would probably allow FlightGear to drive the
Windows-based series 400 simulation software - buying a real GNS430
just as an add on might be somewhat expensive for the casual user  :-)

Please note, while you/we are at it, than "fgfs --help --verbose",
among others, lists the "--garmin=" option, but not the "--AV400=".

Cheers,
Martin.

Will you also commit the Garmin 400, so everybody can download one?

The --garmin= protocol outputs basic NMEA strings with some (a) garmin
extension.

What I am implementing is the ARNAV format which I've also heard called the
AV400 format or RS-232 Type 1.

There is a set of messages that the Garmin 295/296/400/430/530/etc. emit.  I
previously implmented this message set which you can activate with the
--AV400=[...] option.  This works for driving a Garmin 295/296 gps.
However, the 400/430/530 gps expect a different command set from the
simulator which is what I have implemented.

Regards,

Curt.

In which sense is this different from the I/O protocol you enable via
the "--garmin=[...]" switch ?
