Port 7879 - Multiple Connections

[tarbat]

I'm looking for some help in running two programs that both connect to port 7879.

When I connect just one program (Planeplotter), everything works okay.  But when I connect the second program (RB Millog), the second program gets incomplete data.  If I start the two programs in the reverse order (RB Millog then Planeplotter), then it's still the second program (Planeplotter) that gets incomplete data.

Using telnet, I observe the following incomplete data if a program is already using port 7879:
<MODESMESSAGE>
</MODESMESSAGE>
<MODESMESSAGE>
</MODESMESSAGE>

Whereas the normal output from port 7879 looks like this:
<MODESMESSAGE>
  <DATETIME>20081109090706</DATETIME>
  <MODES>3949EE</MODES>
  <ALTITUDE>34000</ALTITUDE>
  <VRATE>0</VRATE>
  <AIRSPEED>493.0</AIRSPEED>
  <LATITUDE>55.6033</LATITUDE>
  <LONGITUDE>-6.7173</LONGITUDE>
  <SQUAWK>493.0</SQUAWK>
</MODESMESSAGE>

So, has anyone else seen this happen?  And is this a Radarbox problem, or something to do with with the way TCP/IP services are configured?  Any help would be much appreciated.

Not really relevant to your problem but, squawks being topical at the moment, that's a rather strange-looking one.

Yes, looks like there is some issue with the data there being sent over the port. We will take a look.

AirNav,

What is the status on the patch for the several port issues? I thought it was planned for November it this still correct?

Not sure where you got Novemeber from, we never mentioned a date. We hope though to have patch release by the end of this year.
