Hi Maurizio,

if you want C example code, try this:

http://www.specs.de/~danni/ap.../index.htm

For byte transmit and receive you can use putchar() and getchar().
Also you can implement your own putchar(), e.g. to a LCD and then you can use printf() to display some text on the LCD, since printf() calls putchar().

If you an assembler expert, use the
#pragma cd
statement. Then you can see on the list file, which assembler code was generated.

Have you read the C51 primer as I suggested on your earlier posting ?

It's really very helpful to understand efficient memory usage.
