Re: [Paparazzi-devel] No throttle in Auto2

[cory barton]

So I disconnected the rf modems, and tried using the ftdi cable, but
the behavior is exactly the same. I think based on the experience with
the usb modem that the gcs is not sending any messages. I am looking
for a way to watch the outgoing messages, but if anyone knows how,
please let me know.
