From 7f71b2c1441877141651d96c9a380bfb32e2ff78 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sun, 10 Jan 2016 20:36:09 -0800 Subject: [PATCH] n_tty: Ignore all read data when closing 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.
