Hi,

What are you confused about? From a programming standpoint, sending and receiving over RS485 will be the same any other serial operation. The only
difference is that you must add the 'Enable' keyword to your #use rs232 statement, and specify a hardware pin to control the direction of data on
the RS485 bus. Typically, you will use a MAX485 interface IC or equivalent.

There are lots of RS485 related threads here on the forum.....
