#74048 - It must be Addressable!
Responding to: ???'s previous message

The microcontroller has only one serial Tx and Rx, so how do I actually go about issuing a command to a particular device without the other devices reacting to that command.

You will either have to have some sort of Addressing scheme, or use some form of Time-Division Multiplexing

If you use your 8051 UART in Mode 3 (Multiprocessor Mode - see my earlier suggestion) then you can have the address recognition all done in hardware with no software overhead.
