Perfect! I should have tried this before. Sorry for making the earlier
noise.
Following is listing of different modes I tried and the outputs. Now, to
be honest, I didn't try to know the logic behind all the options, so I
might be redundant in trying them. If any output is interesting and if I
am required to do more testing, I will be glad to be of help.

Can anyone decipher it for me?
Thanks a lot for all the help.
