Hi, all. In my program i put all you are saying about fast interrupts, and with INT_INT, works fine, and so better than it use with on interrupt goto..... I´ve probed also with TIMR0 at same time and works again. But if i put RX_INT, others work but RX_INT subrutine nothing happens.

I delete all about INT_INT and TIMR0, and works. In RX_INT sub only have a sentence like HSERIN char, and in main program LCDOUT char to see the incoming char.

Any ideas? I copied the code of first page to make it, and it should be work.

Another question: If i want to save that char in a string to display it in the lcd, when carriage return income, how can i do it??? My head it´s warm....... sorry.

Also i´ve read the post about string of Darrel but i´m newby and i don´t undestand so much.

Thanks for all.

PD.- micro it´s 16F877A or 16F876, or 16F84
