				Changes
				-------
Release	ESIL	Description
--------------------------------------------------------------------------------
1.2.2	0931	Handling of modem signal ioctls corrected.

1.2.1	0820	Slave system in Dual-Host Fail-Safe installation will now
		acquire RTAs without having to reboot.

1.2.1	0831	'rioshow' utility now indicates the correct number of ports for
		8 port RTAs.

1.2.1	0854	Driver no longer checks ttymgr's RXOVERRUN flag as this causes
		ports to hang when using software flow control. Data buffering
		now moded only on ttymgr buffer free space.

1.2.0	0763	Installation now uses "host.bin" and "rta.bin" in place of
		older product oriented download binary filenames.

1.2.0	0786	rioinfo.c sources modified to '#include' /usr/include/ioctl.h
		to prevent warning messages during installation.

1.2.0	0787	'config.rio' has been replaced with a new suite of configuration
	0788	tools. Any problems regarding 'console login' after configuring
		a RIO port with config.rio are resolved.

1.2.0	0816	Driver and utilities now support "Dual-Host Fail-Safe"
		installations.

1.2.0	0817	'config.rio' and 'rioadopt' utilities - replaced by a new suite
		of configuration utilities - are no longer installed with the
		driver.

1.2.0	0818	The new suite of configuration utilities includes an application
		to retrieve and display driver statistics information.

1.1.1	0764	'config.rio' modified to display tty names which are numbered
		in a manner consistent with that used for naming RIO device
		nodes in /dev; ie. the first RIO tty is ttyr000.

1.1.1	0775	'rioadopt' is now included in the driver's installable fileset.

1.1.1	0776	'RIO_QUICK_CHECK' ioctl now uses alternative driver parameters
		and returns a non-zero value if no RTA disconnection's have
		been detected, otherwise 0 (zero) is returned. There is no
		relationship between the value returned and any particular RTA
		or the number of disconnection's.

1.1.0	----	As detailed in the product specification, (6240018), RIO LynxOS
		now supports multiple host cards.
		The driver supports upto 4 host cards, which may be a mix of ISA
		and PCI types.

1.0.2	0756	config.rio modified to correctly write /etc/ttys file when
		changes are saved during exit.

1.0.2	0757	Driver modified to allow setting of port characteristics for
		all ports.

1.0.2	0759	Driver modified to prevent ports being "locked out" if opened
		whilst RTA link is down.

1.0.2	0762	Driver and install utility modified to support "Plug and Play"
		for PCI host cards, (if no ISA card defined).

1.0.2	0766	Instead of building the driver from installed source code,
		the installation utility extracts driver object files from
		installed rio_driver.a library (and rio_driver_d.a if
		appropriate) and inserts them into kernel object library(ies).
		The kernel is then re-linked. Driver sources are no longer
		installed.

1.0.2	0760	Driver now identifies its version and configured host cards
		on system console when RIO is 'booted'.

1.0.2	0761	Driver supports hardware flow control using RIO specific
		ioctls.

1.0.1	----	Driver fileset has been rationalised so that it no longer
		overwrites some system header files in /usr/include and
		/usr/include/sys during installation.

1.0.1	----	Driver modified to build for 'Modular Kernel Support'.

1.0.1	----	Config.rio utility now runs satisfactorily on telnet sessions.

1.0.1	----	Install/Uninstall utilities modified for compatibility with
		O/S versions 2.5 and 3.0.

1.0.1	----	'config.rio' sources modified to build when isolated from
		system with driver v1.0.0 installed.
