key to run the bit error test automatically.  
    since its automatic one can run it without any prior knowledge 
    
 on tau, at the command prompt type the followig..  
1-  cd   
    (just to make sure you are at /home/d0stt/)     
2-  source auto_ber_test01.csh 1 1 1 1000 aa1 &    
    ( runs the script auto_ber_test01.csh in the background for almost 2 weeks.  
    1 1 1 are for activating all the 3 channels, viz. 0(or A), 1(or B) and 2(or C).  
    1000 ==N_BLOCK, obtained from the command prompt. I would suggest not to change this.  

If one wants to run the code for a longer/shorter time (ie more/less than 2 weeks)  in the  
script itself there is a variable which allows the code to repeat for  
    nearly 2 weeks. the integer 240 may be changed accordingly.  

aa1 is a temporary log file which is appended to the main log file "..."(ber_test.log) - which  
originates in the script itself.  

after a job is complete the main log file needs to be saved as a different file,  
otherwise when a new job runs, the new data will be appended to the old one.  

3-  grep 'm_cerr' ber_test.log | cat > list.log    
find the relevant lines only from the log file. the lines which have the  
total # correctable and uncorrectable errors are stored into a new file.  
these numbers contain info for errors in all the 3 channels. Please see lrb note  
for more information.  

4- write code to extract errors for each channel.  

- happy testing !
