If anyone has any objections, please let me know. ------------------ From: Annette Kobou [ Upstream commit 47ef5256124fb939d8157b13ca048c902435cf23 ] The polarity of the DE signal of the transceiver is active-high for sending. Therefore rs485-rts-active-low is wrong and needs to be removed to make RS485 transmissions work.
