How can run the simulink in the DSP board and PC computer synchronous?

Hi, I have a problem about the Simulink. I have two target boards (DSP2801) and two computers. I want to connected the two DSP boards together with tcp/ip, but the model based design do not support with the tcp/ip block to generation code. So, I want use the two computers to connected with tcp/ip, and run together with DSP, How can I build a model with two parts Simulink run synchronous, one part run at DSP board (can generation code), another run at my computer (can use the tcp/ip block to connected with each other)?
