From 6de02123bf3e8baeee97fff7efc50bc192332804 Mon Sep 17 00:00:00 2001 From: Alan Cox Date: Tue, 8 May 2007 00:26:21 -0700 Subject: [PATCH] tty: i386/x86_64 arbitary speed support Adds the needed TCGETS2/TCSETS2 ioctl calls, structures, defines and the like. Tested against the test suite and passes. Other platforms should need roughly the same change.
