  We were calling him AORJ and similar renditions for some time because you could never tell who was behind his IRC nickname, it was either (A)nton or (J)eremy.  What is the dragon airplane line?

But Jeremy Tyler is a celebrity and the most helpful contributor to the
project, and a prowd co-owner of the  Dragon airplane line, he is sometimes
called AJ in the chat room for some unknown reasons :)

The Maxstream API protocol (xbee) is most useful for simultaneous 
control of multiple aircraft and requires the xbee_init string to be 
configured and sent to the modem at least once to program 
the ID number 
among other things.  If you have no need for the API 
protocol, the best 
method is to just use transparent serial (pprz) with the modems in 
their default configuration.  They should work right out of 
the box in 
place of your Aerocomm modems without any configuration 
changes at all.  
I do recommend that you set them to a higher baud rate (56K) 
and that 
can be done with the Maxstream software.

with the up 
The down link works normally but i am not able to change block in 
flight plan or anything else that require an up link. It 
doesn't work 
better with my FTDI cable, what makes me think the bug is  in my GCS 
session. The GCS doesn't seem to send anything, the tx led 
on the modem 
isn't blinking. Here is the session i am using:

     <session name="7 Xbee">
       <program name="link">
         <arg flag="-d" constant="/dev/ttyUSB0"/>
  	 <arg flag="-uplink" constant=""/>
         <arg flag="-transport" constant="xbee"/>
  	 <arg flag="-s" constant="9600"/>
       <program name="server"/>
       <program name="messages">
         <arg flag="-c" constant="telemetry:*"/>
       <program name="gcs">
         <arg flag="-mercator" constant=""/>
	<arg flag="-ref" constant="WGS84 53.301387 -60.429488"/>
        <arg flag="-center" constant="WGS84 53.301387 -60.429488"/>
         <arg flag="zoom" constant="0.08"/>

Everything steel work perfect when i use the aerocomm with an 
appropriate session. If anybody have a clue what could cause 
that, please help me.
