I am new to this list.

Can this component, serial RS232, be made to work with RS485 as well and is there an example?

TnrComm component has RS485 mode.
property RS485Mode:boolean;


The RS485Mode property enables a simple RS485 mode for write operations. In this mode RTS will be raised before start the write operation and RTS line will be clear immediately after the end of transmission. The StreamProtocol property should have spNone value if you will set RS485Mode in true.
