Out of interest, Why did you choose to write that in ALL CAPITALS?
It makes it much harder to read, and many people consider ALL CAPITALS to be SHOUTING and, hence, rude.
Before posting to any internet forum, you should always be careful to read its terms to ensure that your question is On-Topic (ie, relevant to the forum).
They are at the top-left of the page, just below the blue band: http://www.keil.com/forum/ http://www.keil.com/forum/terms.asp
Note that Matlab is not a Keil product. Therefore, any questions about Matlab need to be addressed to http://www.mathworks.com/ - they probably have a forum of their own!
For Keil examples, application notes, etc, see http://www.keil.com/support/
For serial comms, start with the "Hello, World" example: http://www.keil.com/support/man/docs/uv3/uv3_ex_hello.htm
All the Keil 8051 manuals are online: http://www.keil.com/support/man_c51.htm

The Association of C & C++ Users (ACCU) has an embedded book review section that you may find useful: www.accu.org/.../embedded_systems.htm
And don't forget the so-called "bible" for the 8051 - these form the fundamental reference for the 8051 architecture:
