I would like to remove modem-manager service from my boot, how can I do it ?
systemctl |grep Modem # (may show ModemManger.service) systemctl [stop|start|enable|disable] ModemManager.service
This worked to disable UML-295 modem from being managed by ModemManger which in turn enabled web-control via http://mbb.vzw.com on CentOS 7.
Check after disabling via:
systemctl list-dependencies multi-user.target |grep Modem
This it looks to work fine:
sudo mv /usr/share/dbus-1/system-services/org.freedesktop.ModemManager.service /usr/share/dbus-1/system-services/org.freedesktop.ModemManager.service.disabled
Instead this doesn't work ( don't know y ):
"echo manual | sudo tee -a /etc/init/modemmanager.override"
The simplest way is to:
sudo apt-get purge modemmanager
Works fine in 12.04 LTS. Nothing in my system had dependencies on modemmanager.
Or you could search for "modemmanager" in the Ubuntu Software Center and remove it from there (the title is "D-Bus service for managing modems").
