Subject: [PATCH] tty: Turn on arbitary baud rate ioctls for i386 platform
Date: Thu, 8 Mar 2007 14:44:45 +0000 [thread overview]
Message-ID: <20070308144445.31a4e3c4@lxorguk.ukuu.org.uk> (raw)
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.
Signed-off-by: Alan Cox <alan@redhat.com>
