Dear all,
i am new to this domain. i am trying to send some data from 8051 microcontroller to the PC. i am using philips P89V51RD2 microcontroller and i am using Keil4.22 version tool to program. i read the 8051 tutorial and configured everyting related for this communication, but still i didn't get the result. Kindly give your guidance to proceed the work further..

Thanks and Regards

The 8051 doesn't do RS232C serial communications, it does TTL serial. Did you convert the TTL data to RS232 with a converter? http://esd.cs.ucr.edu/labs/serial/serial.html

 

Dear all, Thanks for your replies. I found the problem and now it's working fine. Actually i forgot to configure the TR1 bit.
Thanks and Regards
