plz respond how to made the program for 89c51 for sms based home appliance control
& plz do explain every line

 Lazy student!

Is this another lazy student asking for his homework?

 Line-by-line

Too lazy to even think up a meaningful title for the post;

Too lazy to choose the appropriate toolset;

Too lazy to write "please"

Too lazy to even give the vaguest hint of what sort of "appliance(s)" he want to control, and what type of control he wants, how he proposes to connect them to the 89c51 ...

 RE: Line-by-line

i think he describes the content of his brain in his subject.
