The problem here is, the appliance schematics are already designed in such way that pins which can be configured as "native" RTS are not used for RS485 control - the ones that are though may only be used as GPIO flipped by software on transmission start/end for that purpose. We simply cannot change the schematics on production because of this issue alone.
