[Paparazzi-devel] RC-link status indicator in gcs do not work as expecte

There is a strange thing happening with regard the rc-link. First time I turn on the RC-tx, the status indicator in the gcs goes from red to green - as expected. After that, I can turn the tx off and on - without anything happening/changing in the gcs. (I can however control the autopilot/servos as normal when the tx is on).
The same behavious can be seen on the autopilot itselt - if I dedicate one of the leds to display the rc-link status.
This worries me, since I guess the autopilots fail-safe behaviour will not kick in, in case of lost rc-link. I am using a Robbe ppm receiver and a Futaba 7C tx.
Is this normal?
