	* Makefile.am, configure.ac: Add new test to exercise tcgetattr and
	tcsetattr. Does a variety of baud, parity, stop bits, and bits per
	character with the assistance of a special test driver which prints
	the requests.
	* termios01/.cvsignore, termios01/Makefile.am, termios01/init.c,
	termios01/termios01.doc, termios01/termios01.scn,
	termios01/termios_testdriver.c, termios01/termios_testdriver.h: New files.
