From 44607123c4f8393b9fcbbb63274f5f9dcbeaae21 Mon Sep 17 00:00:00 2001 From: Arnaud Patard Date: Tue, 21 Apr 2009 17:39:08 +0300 Subject: Fix struct termios host - target translation When converting the termios structure between host and target in target_to_host_termios and host_to_target_termios, the c_cc[] array is never initialised. Calling memset() before using it allows to run successfully "stty echo / stty -echo" on arm-linux-user target (host being x86 and mips).
