+# 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 ...
+
+# Set the mode for all created devices.
+_opt_defaultmode="0666" # default: 0600
+# If you need more granular control.
+# See http://www.digi.com/support/kbase/kbaseresultdetl?id=3048
+# Once set copy /etc/udev/rules.d/10-dgrp.rules to the PKGBUILD folder
+# and it will be made into the package.
+
+# sudo must be configured and available to the user account
+# In (non root) user account: download PKGBUILD into a new folder
+# using any method: cower or any AUR helper, wget, web browser, copy through network, or paste into PuTTY
+# makepkg -sCcfi
+
+# Since the kernel module isn't loaded until you have an active
+# device, these services are automatically enabled and started

+
+# To get your equipment up faster on servers that don't have Xwindows installed

+
+# make install and other commands described in the release notes
+# only build properly in the Arch environment when you first run
+# "makepkg -sC" to unpack the source allowing this PKGBUILD to patch the build files.
+
+# makepkg switches:
+#  -s = build package
+#  -C = erase source and rebuild from scratch. This is important because once
+#       built it is locked to your booted kernel version. When the kernel 
+#       changes the package is worthless and you must boot the new kernel and
+#       rebuild from scratch. Rebuild automation is provided.
+#  -f = force overwrite of already built package. When the kernel changes the 
+#       the package is worthless.
+#  -c = erase work folders when done
+#  -i = install or upgrade package after build. 
+
+# Leave "-c -i" off if you'd like to perform the make and install yourself
+# using "make install" as described in the release notes.
+
+# If you opt out of the Arch Linux package you must
+# sudo make install
+# sudo make postinstall
+# You will need to construct your own startup environment. 
+# The BSD init scripts run just fine. They just don't launch automatically
+# in systemd. For startup I use @reboot in cron (cronie) to launch a shell 
+# script in ~root with these commands:
+# #!/bin/sh
+# sleep 5 # wait for network and other services to start
+# /etc/init.d/dgrp_daemon start # This submits configured interfaces to the kernel module
+# /etc/init.d/dgrp_ditty start  # this sets configured baud rates and other ditty-rp settings for the ports
+# You won't get a graceful shutdown on reboot.
+
+# In general for any manual upgrade you will need to:
+# sudo make preuninstall # this shuts down all of your interfaces which unloads the kernel module. 
+                         # Then the UDEV module is removed. The config file is not erased.
+# sudo make uninstall    # This removes the old executables, man pages, and other Digi files
+# sudo mandb             # this removes the Digi man page summaries from "man -k".
+# (don't do this) "./configure"   # this rebuilds the makefiles with the new kernel version
+# (don't do this) "sudo make all" # this builds all the new executables
+# (do this instead) "makepkg -sC" # This modifies some files for the Arch Linux package, runs the above two commands, makes a package, then modifies the makefiles for "make install"
+# sudo make install      # this installs all the executables
+# sudo mandb             # this adds the Digi man page summaries and any other missing summaries to "man -k"
+# sudo make postinstall  # this installs the UDEV module and starts any configured interfaces and the kernel module.
+# Adjust your daemon startup as necessary. The @reboot option in cron (cronie) is one choice, see above.
+
+# Note that the kernel module is not loaded until you configure at least one interface. 
+# When your last interface is uninit the kernel module will be unloaded.
+
+# The manual install will not give you a systemd init script and installs unnecessary
+# files and is a bunch of work to rebuild every time the kernel changes.
+
+# How about we don't do that and use the Arch Linux package instead.
+
+# The Arch Linux package gives you
+#  * systemd init scripts
+#  * Only installs the right files
+#  * Automatic removal on kernel upgrade
+#  * Automatic rebuild and start on next login
+
+# Uninstall cleanup: 
+# rm /etc/dgrp.backing.store /usr/bin/dgrp/config/ditty.commands
+# rmdir /usr/bin/dgrp/config
+# rmdir /usr/bin/dgrp
+
+# If Digi releases a new version then all you need to change is
+# pkgver, source, and possibly _pkgnamever

+.TH DRPADMIN 1M "November 1, 1998"
+.SH NAME
+drpadmin - Digi Realport Configuration Utility
+.SH SYNOPSIS
+.TP 14
+drpadmin
+.SH DESCRIPTION
+The drpadmin utility is invoked by the system administrator to
+view, add, remove, or change the configuration of RealPort-enabled
+Products used with the
+.B dgrp
+driver. When invoked by a non root user the current configuration
+is displayed along with any kernel warning messages. Configuration
+is not available to a non root user.
+.PP
+When invoked, drpadmin begins a question-and-answer
+terminal conversation with the user.  The user may
+.B add
+a RealPort-enabled product,
+.B show
+the current configuration and other details provided by the kernel driver,
+.B remove
+a previously configured unit, or
+.B reset
+a previously configured unit
+.PP
+In the
+.B show
+operation, the program simply displays the contents of the
+.I /etc/dgrp.backing.store
+file with the
+.B less
+program.
+.PP
+The show operations are safe to run any time.
+The remaining operations may cause 
+temporary or permanent service interruptions to your Realport devices.
+.PP
+In the
+.B add
+operation, the user is asked for:
+.TP 8
+Remote node name or IP address
+The TCP/IP node name, or the numeric dot-address of the Digi ethernet-based
+serial device.
+.TP
+Number of ports
+The number of tty devices to be created for this unit.
+If this number is less than the number of physical ports,
+only the entered number will be available to the Realport Driver.
+The unassigned ports will be available for other connection types.
+Some Digi products and drivers accept other connection types to assigned ports
+so long as there are no active Realport connections.
+If this number is greater, the additional devices will not be usable
+unless/until the hardware is expanded.
+.TP
+Realport tty device id
+This one or two character alphanumeric string is used to generate
+the 
+.BI /dev/tty XN,
+.BI /dev/pr XN
+and
+.BI /dev/cu XN
+device names for this unit.
+Here
+.I X
+is the entered string, and
+.I N
+is the automatically generated 2 digit port number in the range 01 to 64.
+.TP
+Encryption
+The encryption setting for this unit. If your device does not support
+encryption then encryption should not be enabled or the device will
+not function. Check your device specifications to see if encryption
+is supported.
+.TP
+Network link speed
+This parameter should be specified only when the network connection from
+the system to the remote device includes a WAN link slower
+than 1 MBit/second.
+The user may enter either simply the WAN speed
+(eg 56000 for a 56K Frame Relay link)
+or may enter a complete WAN speed string as documented
+in the
+.BR drpd (1m)
+manual page.
+.PP
+When all data is entered, the
+.B add
+command calls 
+.B dgrp_cfg_node init
+to load the kernel module if not already loaded and
+activate the device. The new device is then immediately available.
+.PP
+drpadmin only configures the most
+common options. Please see the
+.BR dgrp_cfg_node (1m)
+manual page for all available options.
+.PP
+In the
+.B remove
+operation, the user is first asked for the unit ID
+to delete as displayed by the
+.B show
+option.  The command then calls
+.B dgrp_cfg_node uninit
+to deactivate the device with the kernel module.
+When the last device is deactivated the kernel module is unloaded 
+.PP
+The configuration changes take effect immediately.
+.PP
+In the
+.B reset
+operation, the user is first asked for the unit ID
+to reset as displayed by the
+.B show
+option.  The command then calls
+.B dgrp_cfg_node stop
+then
+.B dgrp_cfg_node start
+to reset the device with the kernel module. 
+.PP
+When the
+.B reset
+operation is complete all connections using the device will be reset.
+.PP
+To change the configuration of a remote device,
+the unit must first be removed and then added back
+into the configuration.
+.PP
+.B dgrp_cfg_node stop
+and
+.B dgrp_cfg_node start
+can be used to change the IP address of a configured unit.
