[PATCH] TIOCMBI[SC]

[Yitzchak Scott-Thoennes]

I don't have a serial device to test this with, but it's just selected
parts of the TIOCMSET handling slightly adapted.

2005-08-01  Yitzchak Scott-Thoennes  <sthoenna@efn.org>

	* fhandler_serial.cc (fhandler_serial::ioctl): Implement TIOCMBIS and
	TIOCMBIC.
	* include/sys/termios.h: Define TIOCMBIS and TIOCMBIC

.
