Currently, the following ioctl calls are supported:
- IIOCNETAIF
- Add an ISDN network interface.
This function adds a network interface to the kernel's
device table. This interface can be used just like normal eth interfaces.
- Argument:
- arg should point to a zero terminated string of max. 10 characters.
if arg is NULL, the kernel assigns a name.
- Return:
- On success, the name of the new interface is copied to arg. and the
call returns 0. On failure, an error code is returned.
- IIOCNETASL
- Create a slave interface.
Creates a slave interface for RAW-device
channel-bundling. These devices behave like network-interfaces, execpt they
are invisible to user. Only
ISDN parameters can be controlled,
but no IP-parameters. IP-parameters are inherited from the corresponding
master-device.
- Argument:
- arg should point to a zero terminated string of max. 21 characters
containing two comma-separated names. The first part is the name of an
existing ISDN network device, which will be master. The
second part will be the name of the new slave interface.
- Return:
- On success, the name of the new interface is copied to arg. and the
call returns 0. On failure, an error code is returned.
- IIOCNETDIF
- Delete a network-interface.
This call deletes an existing
ISDN network
interface.
- Argument:
- arg should point to a zero terminated string of max. 10 characters
naming an existing interface which will be deleted. If the interface is a
master interface, all it's slave-interfaces will be deleted also.
- Return:
- On success, the call returns 0. On failure, an error code is
returned.
- IIOCNETSCF
- Set configurable parameters of an ISDN network
interface.
This call replaces all
ISDN related
parameters of an interface by the parameters given.

interface.
This call returns all
ISDN related
parameters of an interface.
- Argument:
- arg should point to a struct isdn_net_ioctl_cfg (defined in

interface.
- Argument:
- arg should point to a struct isdn_net_ioctl_phone which
contains necessary information.

interface.
This call returns the list of phone numbers associated to
an existing network interface.

as a space-separated list of number-strings terminated by a NULL
byte.
- IIOCNETDIL

This call initiates dialing of an
ISDN
network interface, if it is not connected. Normally, this ioctl is not needed,
because
ISDN network interface perform dial on demand by
default.
- Argument:

- IIOCSIGPRF
- Enable signaling on change of modem profiles.
With this call, the calling process is registered to
receive a SIGIO on every change of any register of any ttyI. Thus it can read
register settings and save them to a file. The calling process has to keep the
device open in order to receive notifications. As soon as it closes the
device, registration is deleted.

- On success, the mapping table is set from the given parameters an the call
returns 0.
- IIOCGETMAP
- Get Mapping table.
This call is used to get EAZ/MSN mapping of a lowlevel
driver.
- Argument:
- arg should point to a struct isdn_ioctl_struct containing
the necessary parameters.
- Return:
- On success, the current mapping table of the given driver is returned and
the call returns 0.
- IIOCDRVCTL
- Lowlevel driver ioctl.
This call is used for controlling various lowlevel
drivers. The ioctl-code for this command is assembled by adding IIOCDRVCTL
(128) and the desired driver ioctl-code. Therefore, a lowlevel driver can
understand a maximum of 127 different ioctls.
- Argument:
- arg should point to a struct isdn_ioctl_struct containing
the necessary parameters, especially the driver-Id must be filled
correctly. The arg component inside isdn_ioctl_struct is handed down to
the driver's ioctl function. Its meaning is not defined here and depends
on the lowlevel driver. See documentation for the various lewlevel drivers
for information about driver- specific ioctl.
- Return:
- The return code depends on the driver's ioctl function. Usually, 0 means
no error.
