Subject: Katsutoshi Shibuya (shibuya@mxb.meshnet.or.jp)of BU-Denken Co., Ltd.
 (Sapporo, Japan) submitted the extended console driver for the MVME162LX BSP
 and the POSIX tcsetattr() and tcgetattr() routines. This device driver
 supports four serial ports, cooked IO, and provides a portable base for Zilog
 8530 based console drivers.
