# Digi Realport driver for Arch Linux. See Digi release notes for supported products.

# Build instructions: (Skip these first two sections)

# This only applies if you installed a long time ago when this driver would still
# compile and haven't upgraded in a while. Now this can't be built on Arch without a
# patch so new users skip to the next section.

# This PKGBUILD does not clean up the slop from the Digi supplied make.
# If you have already installed according to the the instructions
# log on as root and go through the process in reverse from the original
# unmodified Digi tgz. You won't lose your configuration.
# make preuninstall; make uninstall
# To clean up you may want to remove the folders /share/ and /etc/init.d/
# Arch Linux does not use these folders though they may have spurious files from
# other misdirected installs.

# The next section: ... Now onto the real install ...

# Edit PKGBUILD.local after the first run

# Once set copy /etc/udev/rules.d/10-dgrp.rules to the PKGBUILD folder
# and it will be made into the package.

_opt_LocktoKernel=1 # Default 1
# 1=Automatic uninstall on every kernel upgrade. Use supplied AutoRebuild to reinstall on next login.

# Since the kernel module isn't loaded until you have a device
# configured, these services are automatically enabled and started
# for immediate hardware support. They will be reenabled each time the
# package is installed or upgraded.
# systemctl enable dgrp_daemon.service
# systemctl start dgrp_daemon.service
# systemctl enable dgrp_ditty.service
# systemctl start dgrp_ditty.service

# To stop these services from loading:
# systemctl disable dgrp_daemon.service
# systemctl stop dgrp_daemon.service
# systemctl disable dgrp_ditty.service
# systemctl stop dgrp_ditty.service

# To get started using your Digi products:
# man -Ik "Digi "
# man dgrp_gui
# man dgrp_cfg_node
# man ditty
# man drpadmin

# The man page for dgrp_cfg_node lacks some detail. See this page for more info
# ftp://digiftp.digi.com/support_archive/support/manuals/psts/rp-linux-conf-managing-portservers-with-dgrp-config-node.html

# To get your equipment up faster on servers that don't have X installed
# I've supplied a console shell script "drpadmin".
# It is adapted from Digi's RealPort "drpadmin" for Sun, HP UX, and SCO and has the same
# look and feel.

# For information about using dgrp_ditty.service to maintain your ditty settings
# across reboots see http://www.digi.com/support/kbase/kbaseresultdetl?id=904

# UnInstall cleanup:
# rm /etc/dgrp.backing.store* /usr/bin/dgrp/config/ditty.commands
# rmdir /usr/bin/dgrp/config
# rmdir /usr/bin/dgrp
