Subject: IXP: enable RTS
X-Git-Tag: v1.3.2-rc1~62^2^2~6

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.
