Hello!
My project write partial bit files(present in CF Card) to ICAP to 
perform partial reconfigurability. It uses serial port to write results 
to PC Hyper terminal. Untill yesterday, it was working perfectly. But 
today there is no data received on hyper terminal / terra term web 
although the is running. I have rechecked my settings again and again 
but there is no error in them.

But the program works properly on a different board. Has anybody any 
idea about what went wrong? is there a need to reload the FPGA 
Configuration files if some configuration data has been modified.

Sometimes, it gives me garbage values and sometimes the terminal just 
stays empty. I have checked the serial cable. There is nothing wrong 
with it. Is there any method to check if there is a hardware problem 
with the board's serial port? Are there any board configuration files 
which I can re-install?

Thanks

Do you have an oscilloscope?

what Lothar wanted to express is that you should do some meassurement to 
make sure if all signals operate
