The Barcode is generated using free 3 of 9 font but its not being scanned even after using start and stop characters like * ....

And exactly what assisitance do you require from the programming community? Check the documentation for your scanner.

There are a couple of possibilities here:
1) The barcode is unscannable.
2) The barcode scanner is not reading the code.

So the first thing you need to do is find out which.
Scan a known-good code - preferably a Code 39 (normal name for 3 of 9 barcodes), but start with one from a packet of peas if you have to. Does the scanner read it?
If it does, then find a Code 39 barcode and scan that. The Wiki page has a couple:[^] - though the quiet zones do look a little thin on the second example.
Does that read?

If it does, then you have a problem with your code - and you need to look at the documentation. Try printing the same Code 39 as you got from Wiki - can you see anything obviously different?

If it doesn't, then check your scanner - it may be setup not to read Code 39 (some are set to read only specific code types - ITF for example, or Traded Unit codes only perhaps). See your scanner documentation.
Refer to this same question & answer on this topic Barcode font size 30 and below not read by the scanner[^]
