Hi Everybody!

I am a Software Programmer and working on a Embedded Project. Unfortunately I am not from Electronics Background, I don't know how a PC serially communicates with a 8051 Microcontroller via an RS-485 chip.

I am in great need of the full circuit of the communication.

Can anybody having the solution provide me with that? I can't pay in terms of money, but I am a software programmer and I can help in this field for free.
