	Add keys to support flow control, line status callbacks,
	hardware breaks and termios.

	* include/config_keys.h: Added generic keys for controlling

2000-07-25  Jonathan Larmour  <jlarmour@redhat.co.uk>

	* include/devtab.h: Define cyg_devio_cwrite, _cread, _bwrite and _bread
	with C linkage

2000-07-21  Nick Garnett  <nickg@cygnus.co.uk>

	* include/io.h: 
	* include/devtab.h: 
	* src/iosys.c:
	Added support for block devices. At present this is really just
	exploiting the perturbations that the EL/IX branch merge will
	cause to add placeholders for future developments.
	These changes consist mainly of adding bwrite() and bread()
	entries in the cyg_devio_table_t structure and adding a char/block
	discriminator flags to the devtab entry status field. API calls
	cyg_io_bwrite() and cyg_io_bread() have also been added.
	Suitable definition of macros means that no existing driver code
	needs to be changed to accomodate this addition.
