# Note: These TODO may not be things I'm planning to fix. Some of them are just
# notes to be fixed by someone else who wants that functionality and warnings
# to those who are expecting that functionality. The HylaFAX+ and AvantFAX
# PKGBUILD have taken many days to get them functional on a modern OS.
# I can't spend a lot more time fixing things I don't use without help.

# TODO: Check Arch Linux in TARGET="...unknown..."
# TODO: More systemd boot support (faxmodem).
# TODO: SendEmail/smtp-cli.pl support instead of sendmail/postfix

# WANT: Enabled Feature List: client, server, send fax, answer fax, answer modem, answer voice
# WANT: CLI fax manager (avantfax?)
# WANT: faxstat how to show only the last n days, like tail?
# WANT: a faxmovemodem: to rename or remove modem without shutting fax system down, compatible with faxmodem and faxgetty.

# TODO: faxcron timer run as uucp. faxqclean must run as root.
# TODO: find more optional dependencies
# TODO: Better default font.
# TODO: Fix faxd-makefile-bug on make install
# TODO: Improve systemd code now that it's out of sed and in patch
# TODO: Remove hfaxd.service and faxq.service symlinks

# TODO: log/c* modem and phone statistics script
# TODO: doneq/q* extended connection info awk script
# TODO: automatic requeue script

# Setting these skel defaults will make adding modems easier.

# Recommended modems

# http://hylafax.sourceforge.net/howto/intro.php#ss1.4

# Some fax documentation recommend against Ethernet serial servers
# because of the unpredictable delays inherent in Ethernet communication.

# Most PCI, PCIe, and USB serial ports are supported. I'm using USB.
# USB is self powered, does not compete for high performance slots,
# and does not create the highly contested /dev/ttyS* or
# /dev/ttyUSB* nodes.

# How to install:

# Before running faxsetup, let's see which daemons we want to run.
# man faxq # used only if modems are present on this system
# man hfaxd # also read the part about SNPP
# Enable the ones you want. faxsetup will start them.
# systemctl enable hylafax-faxq
# systemctl enable hylafax-hfaxd

# sudo faxsetup

# faxsetup will ask to run faxaddmodem only if there are no modems set up. 
# Answer yes if you like but you might as well answer no to
#   Do you want to run faxaddmodem to configure a modem [yes]? no
# because you'll need to run faxaddmodem anyways to add more than one modem.

# You can run with or without faxgetty
# faxgetty makes your setup more reliable and easier to manage.
# faxgetty is suitable for send/receive or send only environments.
# faxgetty is not required. If using faxgetty answer "NO" to
#   Should I run faxmodem for each configured modem [yes]? no
# and enable/start your modems.
# faxmodem systemd support is incomplete. Modems will not autostart on boot.

# What modems are configured?
# ls /var/spool/hylafax/etc/config.tty*

# sudo faxaddmodem
# Add as many modems as you like. See below for some minimally high speed techniques.

# Enable one of the modems with some of the following commands.

# sudo systemctl enable --now faxgetty@ttyUSB0.service
# sudo systemctl enable --now faxgetty@ttyACM0.service

# You only need to enable the first faxgetty service manually. faxsetup will 
# detect that faxgetty is in use and automatically enable and start all 
# configured modems. When all modems are added run faxsetup again to restart 
# the servers and enable all modems.
# Note that all modems are enabled including those that were manually
# disabled 'systemctl disable --now'. To permanently disable a modem
# you must 'rm /var/spool/hylafax/etc/config.tty...'
# To prevent faxsetup from enabling a modem and keep the config:
#   mv /var/spool/hylafax/etc/config.ttyACM1 /var/spool/hylafax/etc/config.disabled.ttyACM1

# sudo faxsetup

# HylaFAX recommends you run faxsetup to restart the servers after every 
# upgrade. This PKGBUILD is programmed to not require this.

# Are the services running?
# systemctl status hylafax-faxq
# systemctl status hylafax-hfaxd
# systemctl list-units 'faxgetty@*.service'
# systemctl list-timers 'hylafax.timer'

# Once you have a modem set up with phone line unplugged
#   sendfax -n -d 5175550113 /etc/passwd
# Once you see that the modem is trying to send, let's see the job.
#   faxstat -s
# Let's delete that job (change the id as necessary)
#   faxrm 1
# Be patient. This can take a minute if the job is active on a modem in faxq.
# Let's see what happened to that job.
#   faxstat -sd
# Try sending a real fax.
#   sendfax -n -d 5175550113 file
# If this doesn't work you'll need to modify dial rules:
#   man dialrules
#   dialtest -a 517 '/var/spool/hylafax/etc/dialrules'
# http://www.hylafax.org/archive/2007-10/msg00152.php
# https://www.allareacodes.com/517
# http://localcallingguide.com/
# dialrules modifications apply immediately, no restarting necessary.

# To remove SGI logo and add your own see
#   /var/spool/hylafax/etc/cover.templ

# After you get a few real faxes sent, let's see how we're performing.
#   xferfaxstats
# Let's see a log file
#   less -S '/var/spool/hylafax/etc/xferfaxlog'

# Avoid restarting the daemons manually with systemctl. Too many commands, and 
# too tricky. Use faxsetup to restart the daemons and enable the modems.

# If the skel defaults are correct and prefab modem configs are available a 
# large number of modems could be automatically set up this way.
#   cd /dev; for i in ttyUSB[1-3]; do faxaddmodem -nointeractive -s 38400 $i; done

# Once the first one is set up, a fast, loose, and minimally tested method for a very 
# large number of identical modems could work like this:
# cd '/dev'
# mdmlist=(ttyUSB* ttyS* ttya[a-m]*) # example 8 USB, 4 serial, 13*16=832 Digi PortServer (dgrp).
# # This is ridiculous of course since there's no single computer with enough 
# # power to run 844 fax modems.
# cd '/var/spool/hylafax'
# for ttymdm in "${mdmlist[@]}"; do
#   if [ "${ttymdm}" != 'ttyUSB0' ]; then
#     cp -p 'etc/config.ttyUSB0' "etc/config.${ttymdm}"
#     mkfifo "FIFO.${ttymdm}"
#     chmod 600 "${ttymdm}"
#     chown 'uucp:uucp' "${ttymdm}"
#     # faxmodem "${ttymdm}"
#     systemctl enable "faxgetty@${ttymdm}.service"
#     systemctl start "faxgetty@${ttymdm}.service"
#   fi
# done

# The HylaFAX binaries work very well. The scripts need major fixes!
# HylaFAX+ is pretty much completely broken for any Linux install,
# and some parts are broken for other Unix too. The original HylaFAX
# is even more broken. I scanned some other package builds:
# [x] dpkg .deb: Debian, Ubuntu
# [x] RPM/YUM spec: RHEL, Redhat, SUSE, CentOS, Fedora, Yellow Dog
# [x] Slackbuild tgz: Slackware
# [x] Pacman PKGBUILD: Arch Linux
# [x] Portage ebuild: Gentoo, Sabayon
# [ ] Ports: FreeBSD
# These have a few well chosen ./configure options but no substantial sed hacks 
# of any kind. I'm wondering how anyone gets HylaFAX running.
# HylaFAX was designed to be an easy install, 
# and with a little sedery, it can be again.
# -CJS

# Note: I only send faxes. Fax receiving might need a bunch more patches.

  # Var $TTY clashes with the Arch Linux environment and likely all other Linux 
  # too. $TTY contains the terminal device from `tty`. With this already set 
  # to a known valid terminal, faxaddmodem never asks for a modem device and 
  # immedately tests the terminal for a modem. We haven't used modems for 
  # terminals for a long time and even when we did, you can't test a modem 
  # while it's "off hook" actively running a terminal. This bug blocks the 
  # to add modems interactively by running faxaddmodem or faxsetup leaving
  # big hole of complexity in setting up HylaFAX+.
  # Until we fix this, automatic modem setup in faxsetup must be skipped.
  # Modems can only be added with "faxaddmodem ttyUSB0". Then you need to run
  # faxsetup again to start all the modems.

  # We change TTY -> MDMTTY instead of -> TTYMDM to prevent sed recursive replace.

  # "faxaddmodem /dev/ttyUSB0" adds the device as "config._dev_ttyUSB0". This 
  # would be clever if the scripts could handle this, but they can't. We'll trim 
  # /dev/ off so the scripts work. It is too much to ask installing admins to 
  # remember to leave /dev/ off when no screens specify such. If the device 
  # is outside of /dev/ then we leave the folder intact resulting in a device
  # like "config._proc_stuff". I'm certain this won't work but 
  # until someone finds a use for a device outside of /dev 
  # this set of bugs will stay the way they are.
  # Fix bugs in /dev/tty* handling. Make faxaddmodem /dev/ttyUSB0 behave the 
  # same as faxaddmodem ttyUSB0. 
  # With all these bugs fixed you can install HylaFAX+ the way it was 
  # originally designed, and it's not very hard.
