Hi, Can you Help me about this problem: I want to have a second software uart But written in "C" and modified to work with INT0 or INT1 for detect receiver incoming data.. Maybe this i true way : www.atmel.com/.../doc3ab877f2ec329.pdf , but this code is assembler. Thanks and The Best Wishes !
Yes my processor (AT89C51RD2 or AT89C55WD) has INT0 and INT1 external interrupts that supports high to low and lo to high interrupt. About transmission times for start bit , stop bits data bits on all 8051 has 3 timers and one can manage these times.
P.S Solution for my problem it's : smartdata.usbid.com/.../an446.pdf but I can't merge to work together with KEIL c51 IDE.
I can't merge to work together with KEIL c51 IDE. WHY NOT?

Because I've never been programing assembler for 8051 cpu.
Most people who complain are beginners, do not know even 1% of the programming language, do not know what it means to machine code, do not know anything Assembler or C do not even know how to find their own bugs (not even know how to program), in short, they want everything on a silver platter without minimal effort and still complain.
Honestly, do me a favor! Enter a programming course, wait a couple of decades, and return to the forum to discuss about it or even complain about something.
Regards to all, and thank those who burn their neurons for all us poor mortels.
Wait a couple of decades? You can manage lots of tasks after some months - bright students soars while the less bright spend time harvesting solutions on the net.
The decades are needed to get disillusioned by the state of mankind ;)

the purpose of this forum is to help others solve a specific detail of a problem, not "teach how to use Keil"
Ok ,never mind! Thanks for all answer and join! If I made this solution working,I'll post some code.
The Best Wishes!
