From 33e745a192c272130b02b86d5dea5b577a291ed7 Mon Sep 17 00:00:00 2001 From: Hendrik Brueckner Date: Tue, 2 Jul 2013 17:07:14 +0200 Subject: tty/hvc_console: Add DTR/RTS callback to handle HUPCL control Introduce a new callback to explicitly handle the HUPCL termios control flag. This prepares for a follow-up commit for the hvc_iucv device driver to improve handling when to drop an established network connection. The callback naming is based on the recently added tty_port interface to facilitate a potential refactoring of the hvc_console to use tty_port functions.
