Subject: [PATCH v2 16/22] usb: serial: ti_usb_3410_5052: Raise DTR and RTS flags if speed is not null anymore
Date: Tue, 26 Jul 2016 19:59:56 +0200 [thread overview]
Message-ID: <20160726180002.2398-17-m.othacehe@gmail.com> (raw)
In-Reply-To: <20160726180002.2398-1-m.othacehe@gmail.com>
If speed is non null anymore, we can raise DTR and RTS flags in
ti_set_termios.
