Upgrading from CAC DPT Release 0.91 or earlier
==============================================================================

Early releases of the CAC DPT software used device names of the form
/dev/pci0a, /dev/pci0b, /dev/pci0c, etc. Releases after 0.91 use names of
the form /dev/dpt0, /dev/dpt0a, /dev/dpt0chan, etc, where dpt is an
abbreviation for Desktop PCI Telephony. The pciopen(3X) and pciopenex(3X)
library calls support both name formats, both in their devname arguments
and in the dev directory.

In the examples below, 'system%' is used as the normal user prompt and
'system#' is used as the superuser prompt. Pseudo variables are used for
paths as follows:

    $build_dir		Root of build tree from post-0.91 release
    $path_to_redist	Location of files redistributed from the development
    			system to the production system

Upgrading the Development System
==============================================================================
The driver makefile automatically handles the transition in device names.
Simply follow the normal installation procedure:

	devel% cd $build_dir
	devel% su
	Password:
	devel# make install-drv
	devel# exit

You should now have entries in the /dev directory like:
	
	devel% ls /dev/dpt[0-9]*
	/dev/dpt0@      /dev/dpt0chan@  /dev/dpt1@      /dev/dpt1chan@
	/dev/dpt0a@     /dev/dpt0tdm@   /dev/dpt1a@     /dev/dpt1tdm@
	/dev/dpt0b@     /dev/dpt0vsp@   /dev/dpt1b@     /dev/dpt1vsp@

There should not be any devices left with the old names:

	devel% ls /dev/pci[0-9]*
	ls: no match

==============================================================================
Installing/Upgrading the Driver on a Production System
==============================================================================
If you do not have 'make' and the source tree available on the production
system you can do the following:

	devel% cd $build_dir/soldev
	devel% make package
	devel% cp dpt_soldev-0.94.tar.gz $path_to_redist
	devel% rsh production
	Password:
	production% cd $path_to_redist
	production% gunzip -c dpt_soldev-0.94.tar.gz | tar xvf -
	production% cd dpt_soldev-0.94
	production% su
	Password:
	production# ./install.sh
	production# exit

You should now have entries in the /dev directory like:
	
	production% ls /dev/dpt[0-9]*
	/dev/dpt0@      /dev/dpt0chan@  /dev/dpt1@      /dev/dpt1chan@
	/dev/dpt0a@     /dev/dpt0tdm@   /dev/dpt1a@     /dev/dpt1tdm@
	/dev/dpt0b@     /dev/dpt0vsp@   /dev/dpt1b@     /dev/dpt1vsp@

There should not be any devices left with the old names:

	production% ls /dev/pci[0-9]*
	ls: no match
