Oops,
I must admit that I was not aware of that thread. Mea culpa!
I will go through those arguments and see if I can take some
effort from that.
Again, I will not take care of any software RS485 and I will
never use any name that contains RTS.
I will also keep my ioctl implementation instead of any termios stuff
- when nobody contradicts.
