From 61f5657c50341198ff05e375e6f1fc0476556562 Mon Sep 17 00:00:00 2001 From: Vitaly Bordug Date: Sat, 29 Apr 2006 22:32:44 +0400 Subject: [PATCH] ppc32 CPM_UART: Fixed break send on SCC SCC uart sends a break sequence each time it is stopped with the CPM_CR_STOP_TX command. That means that each time an application closes the serial device, a break is transmitted. To fix this, graceful tx stop is issued for SCC.
