hi vikas,
              Thanks for replying and going through my mail. As suggested by
marcel , now i am using rfcomm sockets directly without using virtual tty
layer and till now (fingers crossed) things are working fine. Example code
in rctest.c really helped a lot.

By the way i am sending file using obex_push service by calling pi from open
obex.What i was doing was , through the code i wrote above , i made a device
special file , which i then passed to the obex pi for performing obex push.
Now instead of passing the file path i am passing the rfcomm socket id
directly which is working fine.I hope this is the right way of doing things.

regards
siddhant
