Date: Thu, 18 Feb 2016 10:18:38 +0300 From: Ильяс Гасанов <torso.nafi@...il.com> To: "Matwey V. Kornilov" <matwey@....msu.ru> Cc: Greg KH <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.com>, Peter Hurley <peter@...leysoftware.com>, Andy Shevchenko <andy.shevchenko@...il.com>, One Thousand Gnomes <gnomes@...rguk.ukuu.org.uk>, linux-kernel <linux-kernel@...r.kernel.org>, linux-serial@...r.kernel.org Subject: Re: [PATCH v8 3/3] tty: 8250_omap: Use software emulated RS485 direction control Also, forgot to mention that if serial8250_em485_init is called not upon uart startup but elsewhere (upon port register for example), and em485 is set, serial8250_do_startup should call serial8250_em485_rts_after_send, or else RTS might be in wrong state whenever the port device is opened, making it impossible to receive data through RTS-controlled RS232<->RS485 hardware converters.
