UNIX IRAF/FIO device driver for the IIS Model 70
(will probably also work for the model 75).  11/85 dct
----------------------------------------------------------------------

This directory contains the IRAF/FIO driver subroutines for the IIS Model 70
image display on UNIX.  On a UNIX system the ZIFOBF (binary file) driver is
used to access the display, hence the subroutines herein merely map the calls
into the corresponding BF procedures.


Driver Procedures:

	zopm70	-- open + allocate
	zclm70	-- close + deallocate
	zrdm70	-- asynchronous binary read
	zwrm70	-- asynchronous binary write
	zwtm70	-- wait for i/o completion, return status
	zstm70	-- get device status
