From 96bd462942022e4569b582c072a0ed26de1cd19b Mon Sep 17 00:00:00 2001 From: Michael Schwingen Date: Thu, 10 Jan 2008 14:59:46 +0100 Subject: [PATCH] IXP: enable RTS enables the RTS signal with CONFIG_SERIAL_RTS_ACTIVE. No handshaking is done, but the active RTS signal allows to connect to the target using a PC which is using RTS/CTS handshake, and does no harm if the PC is set to ignore RTS.
