Subject: [PATCH 2/9] n_tty: Ignore all read data when closing
Date: Sun, 10 Jan 2016 14:43:02 -0800 [thread overview]
Message-ID: <1452465789-4039-2-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1452465789-4039-1-git-send-email-peter@hurleysoftware.com>
On final port close (and thus final tty close), only output flow
control requests in the input data should be processed. Ignore all
other input data, including parity errors, overruns and breaks.
