Starting Hylafax+ on bootup under OpenSuse

I've been running/maintaining hylafax on ubuntu/debian systems so OpenSuse
is new to me

What do I need to do to have hfaxd, faxq, faxgetty run at startup of
OpenSuse?

I followed the instructions here:
http://hylafax.sourceforge.net/howto/install.php
specifically 2.2.5, for systemd

On systems using systemd the same is done by creating a file such as
/etc/systemd/system/faxgetty-ttyS0.service that looks like this:

[Unit]
Description=HylaFAX faxgetty for ttyS0

[Service]
User=root
Group=root
Restart=always
RestartSec=30
ExecStart=/usr/sbin/faxgetty ttyS0

[Install]
WantedBy=multi-user.target

Then issue 'systemctl start faxgetty-ttyS0.service' to start up that
faxgetty process. If you want it to start at boot-time then issue 'systemctl
enable faxgetty-ttyS0.service'.

I am confused by: at boot time then issue "systemctl.....
As root, I entered:systemctl enable faxgetty-ttyACM0.service  (I am using
usb modem)
and everything looked ok, but hylafax does not start at boot...

Any advice/help really appreciated
Thanks
John
