Is it possible to use the ARMWSD.exe serial downloader over RS485?

I am using an ADuC7021 on a board that is available in two configurations: RS232 and RS485. I presumed that the bootloader would work on both versions of the board, as none of the documentation I could find said it wouldn't.

 

While the blackspace character is correctly received and synchronised, and the reply correctly sent, it never actually reaches the comms bus as RTS is disabled and hence permanently in receive.

 

- Is there a setting for ARMWSD that will enable RTS?

- Any other crazy ideas to get this working? (board re-layout is an option at this stage)

 

Thank you, Kristin
