The easiest way, build a big chain: TXD to RXD of the next and so on.
Then no awkward protocol must be used, since no collision can occur. Its suggested to use the 9 bit mode to address and unaddress a device. Any device which receive data if it was not addressed, simple transmit it to the next: "MOV SBUF, SBUF". Any device, which want to transmit something must establish a receive buffer during this time.
