       om  provides  a  command line interface to various OpenMoko specific
       pieces of hardware.  Note that om talks directly to the  kernel  and
       might  not  properly co-exist with fso-frameworkd that also wants to
       control the same pieces of hardware. However, using om to  read  the
       state of the hardware should be safe even when using fso-frameworkd.

       om backlight
              Read  backlight  brightness.  This is an integer between zero
              and what om backlight get-max returns. Reports  true  bright-
              ness  only  if the screen has not been blanked with om screen
              power 0.

       om backlight get-max
              Get maximum value of brightness, usually 255.

       om backlight <brightness>
              Set backlight brightness.

       om touchscreen lock
              Locks touchscreen and waits for any signal to unlock it. This
              is useful when you want to keep the phone running in a pocket
              and don't want the backlight to turn on every time you  acci-
              dentally touch the screen. Locking is done in a way that does
              not depend on X so if X  server  crashes  and  restarts  your
              screen will still stay locked.

       om screen power [1/0]
              Reads  or  sets the power state of the screen. Note that Xorg
              and fso-frameworkd do not know how to read the  power  status
              of  the screen (frameworkd reads it on startup only). If Xorg
              turns the screen and after that you turn the screen off  with
              omhacks  then  touching  the  screen won't turn the screen on
              (Xorg thinks the screen is still on and does  not  bother  to
              try to power it on).

       om bt [--swap] power [1/0]
              Reads or sets the power state of bluetooth. Bluetooth is con-
              nected to USB bus so it might take a while for it  to  appear
              in lsusb and be usable after power on.

       om power
              List the power status of various devices.

       om power all-off
              Disable power to bluetooth, GSM, GPS and WLAN.

       om gsm [--swap] power [1/0]
              Reads or sets the power state of GSM.

       om gsm flowcontrol [1/0]
              Reads  or sets the state of GSM flowcontrol. When flowcontrol
              is enabled GSM chip will generate an interrupt  when  it  has
              data and will not try to send it over serial port until flow-
              control is disabled. Enabling flowcontrol before suspend  and
              disabling it after resume is required to make sure no data is
              lost during suspend.

       om gps [--swap] power [1/0]
              Reads or sets the power state of GPS.

       om gps [--swap] keep-on-in-suspend [1/0]
              Reads or sets the flag that causes GPS  to  stay  powered  on
              during  suspend.  This  is useful if you want to keep GPS fix
              during suspend.

       om gps send-ubx <class> <type> [payload_byte0] [payload_byte1] ...
              Send arbitrary UBX protocol command to the GPS chip.   Please
              read  "ANTARIS_Protocol_Specification(GPS.G3-X-03002).chm" to
              understand the protocol. Here are examples of  commands  that
              are tested to work:

              class   type   payload             description
              06      01     f0 01 00            disable GPGLL messages
              06      01     f0 02 00            disable GPGSA messages
              06      01     f0 03 00            disable GPGSV messages
              06      01     f0 05 00            disable GPGTG messages
              06      01     f0 08 00            disable GPZDA messages
              06      08     fa 00 01 00 00 00   report position 4 times/s
              06      08     f4 01 01 00 00 00   report position 2 times/s

       om wifi [--swap] power [1/0]
              Reads or sets the power state of WLAN.

       om wifi maxperf <iface> [1/0]
              Reads  or  sets  the  maxperf  mode  of  WLAN.  Enabling this
              increases energy consumption but lowers  latency.  Note  that
              root  privileges  are  not currently required for tuning this
              wifi parameter so a local user can cause  DoS  by  constantly
              disabling maximum performance mode.

       om battery temperature
              Reads battery temperature. Units are degrees Centigrade.

       om battery energy
              Reads the current energy percentage of the battery.

       om battery consumption
              Reads  the  current energy consumption as measure by the bat-
              tery. Units are microamperes. Negative value  indicates  that
              battery is being charged.

       om battery charger-limit [0-500]
              Reads  or  sets  the upper limit for battery charger current.
              Units are milliamperes.  Normally USB charger limit and  bat-
              tery charger limit have the same value. However, sometimes it
              is useful to charger battery very slowly or not  at  all  and
              still  power rest of the system from USB. This allows one for
              example to keep battery at its recommended  storage  capacity
              of 40% without having to physically remove the battery.  Note
              that kernel will round the limit to  nearest  suitable  value
              which  is  usually a few milliamperes lower than the supplied
              limit. Changing USB charger limit will reset also this  limit
              to the same value so you must first set the USB charger limit
              and only then the battery charger limit.

       om resume-reason
              Read the reason for the most recent resume. If there are mul-
              tiple resume reasons they are separated by newlines. Possible
              values include (but are not limited to)


       om resume-reason contains <val>
              Checks if resume reasons include the given string.

       om led Lists the state of all LED devices.

       om led <name>
              Lists the state of the given LED device.

       om led <name> <brightness>
              Sets the brightness of the given  LED  device  to  the  given
              brightness.  Brightness  is an integer from 0 to 255 but only
              the vibrator device really cares about the brightness value.

       om led <name> <brightness> timer <ontime> <offtime>
              In addition to above also makes the  LED  blink.  Ontime  and
              offtime are in milliseconds.

       om uevent dump
              Dump uevent events to stdout.

       om usb mode [device|host]
              Read  or  set the USB mode. In device mode the phone can talk
              to USB hosts (PCs or phones in host mode). In host  mode  the
              phone   can  talk  to  USB  devices.  See  also  the  om  usb
              charger-mode option.

       om usb charger-mode [charge-battery|power-usb]
              Reads or sets the USB charger  mode.  Normally  you  want  to
              charge  the  battery  in device mode and power the USB bus in
              host mode but it is possible to for example use  an  external
              battery  power  the  USB bus so that the phone can be in host
              mode and still charge itself over USB.

       om usb charger-limit [0|100|500]
              Reads or sets the charger limit of USB.  Units  are  in  mil-
              liamperes  and  control  the current that the phone will draw
              from the USB bus. When the phone is in device mode  and  some
              gadget driver is loaded it will negotiate the highest allowed
              charging current automatically. However, if you are  using  a
              dumb  external  USB  battery  it  might be necessary to force
              larger limit than the default of 100 mA. Do not set the limit
              to be too large if your charger can not handle it!

       om sysfs name [name...]
              Shows  the  sysfs path associated with internal om path. This
              option is only useful for debugging om itself. Here are  some
