Date: Wed, 30 Sep 2009 12:18:32 -0400 From: leitao@...ux.vnet.ibm.com To: linux-kernel@...r.kernel.org Subject: [PATCH] jsm: fixing termios structure to be compatible with stty application Currently stty returns "unable to perform all requested operations", when it changes the speed of a jsm device. It was happening because c_ispeed and c_ospeed were not set properly. This patch just set them, so that when stty compare the requested and the new mode(struct termios), they are the same.
