    one wire serial data transfer with 8051(not serial port)

    Hey! every1 :D how are u guys doing?
    I am here wid my problem.
    so here it goes.. i have two 89s52 and i want to transfer data between them by using serial data transfer, I want to use any pin of the Uc to trsnfer the data. I have tried many programming but somehow its never working. I want a Uc to trnx it and another want to rxEv it and display it. (i am doing this by bit shifting not by its original serial TXD and RXD ports.)
    Does anyone have any idea? Please suggest me.

    I am using Keil c and 11 Mhz Xtal.

    Thank you!

    you could use a 1 wire protocol similar to the iButton
    1-Wire - Wikipedia, the free encyclopedia
    1-Wire and iButton - Maxim
