as i said, i'm new in this. i've read the bible, the tutorial and 3 documments about 8051. sometimes we need someone who clears some doubts, that's why we ask for help. i thougth i've understood "the simpliest facts about serial communication with the '51" but there was a few things that i didn't get so well. sorry i'm not too fast for learning. is true "you have to learn to crawl before you learn to walk" but with dificults excercises we learn more than with the simple ones. i saw 5 examples about uart modes in keil. but i didn't understand too much this examples and didn't see how can i modified them to make what i want, so i tried to make something and in the road i've found troubles and tried to resolve them by myself but i couldn't. so that's why asked for help.


thanks,

Ruben Porras.
