27 Dialing, hangup, general provider online/offline state control.
29 Copyright: 2017 Intra2net AG
31 This used to be part of the sysmisc utilitiy initially which caused an include
32 circle with the arnied wrapper.
36 ------------------------------------------------------
38 Generic access to the system’s dialing mode. Allows for requesting manual
39 or permanently online dial state.
42 Enter permantly online dialing state.
45 Enter dial on command state.
48 Terminate uplink unconditionally.
50 All API methods come with the optional argument ``block`` (bool) to request the
51 call to block until the system completes the state transition successfully. The
52 completion timeout is currently 10 seconds (see the definition of
53 ``DIALTOOLS_TIMEOUT`` below).
