Hi Christopher, I checked all your referenced threads. Here is my summary: 1) RS485 seems to be an issue for several people. 2) enabling hardware RS485 via ioct is never totally dismissed. 3) Discussion about software direction control will never end. So I suggest not to mix hardware and software direction control as the same issue. When the hardware supports direction control we should implement it as ioctl. Even this sounds a little bit egoistic, it might bring us a little forward. I will update my initial patch and consider Laurent's comments.
