Subject: [PATCH v3 4/9] n_tty: Factor ISTRIP and IUCLC receive_buf into separate fn
Date: Wed, 24 Jul 2013 08:29:52 -0400 [thread overview]
Message-ID: <1374668997-29726-4-git-send-email-peter@hurleysoftware.com> (raw)
In-Reply-To: <1374668997-29726-1-git-send-email-peter@hurleysoftware.com>
Convert to modal receive_buf processing; factor char receive
processing for unusual termios settings out of normal per-char
i/o path.
