Thanks to P Dawson -- plugin looks great. I'm using it with the Garmin 396 and after a few minutes of maneuvering, the garmin seems to detach from the serial data because it just stars flying straight and level without response to maneuvering in FS2004. I have GPSOut 2.601 and my config is
Sentences=AV400
Interval=1000
Port=COM1
Speed=9600
I have to restart the 396 to get it to follow FS2004 again. Oddly, the 396 (firmware 2.70) has locked up twice while the serial data was coming in, so I'm going to try increasing the interval.
When I connect the FS PC to minicom on my laptop, the data looks like its coming faster than every 1000ms.
The next day...
I've updated the Firmware to 2.92beta and the unit seems to be following FS2004 much better. I can even pause the simulator now (396 used to keep flying straight and level).
It would be great if traffic data (TIS-like) could be output over AV400 from FS2004, but I think the GTX330 uses NMEA or something proprietary.
Thanks again Pete!
