From fcc8ac1825d3d0fb81f73bc1a80ebc863168bb56 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Thu, 11 Jun 2009 12:24:17 +0100 Subject: tty: Add carrier processing on close to the tty_port core Some drivers implement this internally, others miss it out. Push the behaviour into the core code as that way everyone will do it consistently. Update the dtr rts method to raise or lower depending upon flags. Having a single method in this style fits most of the implementations more cleanly than two funtions.
