Finally it worked.. I soldered a 8051 in system programmer and after 3 trips to lamington road heavens took mercy upon me! 15 days I spent debugging a perfect circuit and it never occured to me that connecting wire was the problem.
In market a USB programmer costs above 2700 Rs.
By the way.. a tip here: DIY kit from vegakit costs 160 Rs which has a serial port and you can use a BAFO RS232-USB convertor (160 bucks) here and save a lot..
This business seems profitable.. Maybe I should give it a thought ;-)
