[sumo-user] Problems with TraCi Communication

[Jens F. <fa...@me...>]

Hello,

I am writing a traci client. And now I have some problems, and I hope  
someone out there can be helpfull.

For reasons of speed I try to bundle a lot of cammands into one TCP  
packet. When I understood the message format correct, than we can put   
2^32 bytes of commands in one message, right? because the message  
begins with an 32bit integer for message length:
http://sourceforge.net/apps/mediawiki/sumo/index.php?title=TraCI/Protocol#Messages

I am bundling 4000 commands @ 14 bytes in one message and now I get  
weird responses. On http://sourceforge.net/apps/mediawiki/sumo/index.php?title=TraCI/Protocol#Status_Response 
  it's said that there are 3 possible response types: 0x00, 0xff and  
0x01, but I get an 0x0C What does that mean?

And I also get only 256 responses. Could it be that I can't send more  
than 256 commands even if the length suggested I can send 2^32  
commands? The responses first 3 bytes look alway like this:

first an integer incremented with each response
second 0x0D
and third 0x0C

My Commands are all Scenario commands to ask the names of alle edges.

Kind Regards
