From a1dd30e9b4c38a4a177106741b03ac6a55777286 Mon Sep 17 00:00:00 2001 From: Peter Hurley Date: Sat, 15 Jun 2013 10:21:26 -0400 Subject: [PATCH] n_tty: Special case EXTPROC receive_buf() as raw mode When EXTPROC is set without ISTRIP or IUCLC, processing is identical to raw mode; handle this receiving mode as a special-case of raw mode.
