Thanks Oli, it works OK with:

$ cat /etc/init/modemmanager.override
start on starting dbus
stop on stopped dbus

I think network-manager is only needed if you want to establish an Internet connection over the HSDPA modem or so.

In this case I only use it to send SMS, etc. so I don't need networking.

Yes, it is:

Thanks Oli, that sounds reasonable. I tried it but:

$ service modemmanager status
modemmanager stop/waiting

$ dmesg |grep -i modemmanager
[    2.888050] init: modemmanager main process ended, respawning
[    2.923251] init: modemmanager main process ended, respawning
(...)
[    3.731722] init: modemmanager respawning too fast, stopped
a wild guess would be that modem-manager uses dbus, so adjust yopur
"start on" accordingly ... any perhaps it can not work at all without a
running network-manager, are you sure it can ?
also look at the upstart job log for your modem-manager job ... they
live in /var/log/upstart, that should have actual error messages.


$ cat modemmanager.override
# modemmanager - modem manager

description     "modem connection manager"

start on startup
stop on runlevel [!2345]

do not put the stuff below into your override, the .conf file already
covers it ... override files only replace the bits you define. just
leave the exec and whatnot as it is defined ... you only want start on/
stop on in your .override ...

respawn

pre-start script
      [ -x /usr/sbin/ModemManager ] || stop
end script

exec /usr/sbin/ModemManager


ciao
