I am trying to run the example program mqx\examples\rs485\rs485.c. As the prorgram is using ittyd port so i have set #define BSPCFG_ENABLE_ITTYD      1 in user_config.h bsp file. I am unsuccessful in exeucting the program. I have opened serial port of my pc to recieve and send data but no transactions are happening. I want to know what are all the settings need to be done to execute rs485 program. 


I have TWR-SER board and set jumpers J17, J18 and J19 in pos 2-3 and i've installed three jumpers on the J13 header on pos 1-2 , 3-4 and 5-6.
