DESCRIPTION

	FIFO: is like PIPE: but is based on fifo.library rather than
     	its own implementation.  Fifo.library is a general fifo
     	library implementation that supports named fifos, writing to a
     	fifo from a hardware exception, multiple readers on a fifo
     	with each getting the same data stream, efficient reading, and
     	automatic or manual flow control.  Programs that require
     	non-blocking IO can access one side of a FIFO: connection via
     	the fifo.library instead of the FIFO: handler.

	Includes source.

	Now programmers of getty, telnetd, remote shells etc.: stop
	writing custom DOS handlers and use fifo.library and FIFO:
	instead, you'll get all the benefits of a common handler.
	Emacs, AUUCP and other programs already use it.

	FIFO source might be of interest to programmers, topics include:
	o interactive DOS handler, CON/AUX: like
	o library creation, even with GCC+Libnix yet 1.3 compatible
	o deep use of GCC inlines and GCC-specific optimizations
	o usage of PA_SOFTINT port arrival action
	o usage of SIGB_SINGLE signal bit

EXAMPLES

	NewShell FIFO:shell1/rwkecs
	Run >NIL: RemCLI shell1
	Run >NIL: Type FIFO:shell1/rmt TO CON:0/11/500/150/Tee_output

NEW FEATURES

	o corrected ACTION_WAIT_CHAR (with timeout).
	o corrected ACTION_SCREEN_MODE.
	o recognizes CONSOLE:
	o ACTION_CHANGE_SIGNAL, ACTION_IS_FILESYSTEM, ACTION_SEEK.
	o many error checks and error return codes.

SPECIAL REQUIREMENTS

	OS 1.3 is still supported (untested).
