Hi all, 

I am back and continue the work on my final year project. As I did stop to work 
on my autopilot the old system was used and all my stuff worked just perfect. 

Yesterday I did update and now I am using the current system based on 
subsystems. The problem I have now is that I does not have communication 
between the modems. I have Xbee pro (series 1) modem. The error I can see in 
GCS window is

Run '/home/uav/paparazzi3/sw/ground_segment/tmtc/link  -d /dev/paparazzi/xbee 
-transport xbee -s 57600'
Run '/home/uav/paparazzi3/sw/ground_segment/tmtc/server '
Run '/home/uav/paparazzi3/sw/ground_segment/cockpit/gcs '
Failure("Error opening modem serial device : fd < 0 (/dev/paparazzi/xbee)")
Broadcasting on network 127.255.255.255, port 2010

DONE (exec /home/uav/paparazzi3/sw/ground_segment/tmtc/link  -d 
/dev/paparazzi/xbee -transport xbee -s 57600 2>&1

I suppose it is something wrong in the codes, but the issue can't be found. My 
modems are set up with baud 57600.They worked just fine with old system, I am 
pretty sure that no farther changes are required for new subsystem. I am using 

<!--Communication -->
<subsystem name="telemetry"  type="transparent">
  <param name="MODEM_BAUD"   value="B57600">
</subsystem>

code in my airframe file. 

Any ideas what should I change to avoid the error message?

Thank you.

Regards, 

Roman
