Really I was taking a rest from my project because I felt tired. I here again. OK, first good news is I am using a ECHO CHARACTER program that someone of you sent me, is working, I can see the the characters that I am sending but just with my user interface program developed with VISUAL BASIC 6.0, when I use hyperterminal I can not see anything, I configured correctly but don't works with hyperterminal.
On the ohter hand, I saw that AT80C52 go to IDLE MODE ALONE, I need reset to begins the process. Do you know something about it?

thanks guys, I keep going yet.........
