CRIO serial data sending problem

Hi all,

 

   i'm using NI 9780 module for  serial communication.

 

   my code is using DMA FIFO at the FPGA level, and read , write vis taking references from these FIFOs 

  

   i have a problem to communicate with one device, (working with a baud rate 19200).

   

   i have to send a list of strings like "S1\n\S2\n.......\n"  via the host main vi  

   but the problem is that i'm receiving "unknown command " or "special character, i'm sure that the trame is not propoerly sent to the FPGA FIFO and there is some modification to do just after string send 

   

   what is your openion?

 

Regards,

sasa
