From 56ce9e2b2463b3b257098aa966586701d9967f1e Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Mon, 13 Oct 2008 23:12:49 +0000 Subject: [PATCH] hvc_console: Add tty driver flag TTY_DRIVER_RESET_TERMIOS After a tty hangup() or close() operation, processes might not reset the termio settings to a sane state. In order to reset the termios to its default settings the tty driver flag TTY_DRIVER_RESET_TERMIOS has been added. TTY driver flag description from include/linux/tty_driver.h: TTY_DRIVER_RESET_TERMIOS --- requests the tty layer to reset the termios setting when the last process has closed the device. Used for PTY's, in particular.
