    NAME

    isdnctrl - ISDN control device
     
    

    SYNOPSIS

    #include <linux/isdn.h>  

    DESCRIPTION

    /dev/isdnctrl is a character device with major number 45 and minor numbers 64 to 127. It allows controlling functionality of the Linux ISDN subsystem.  

    IOCTL FUNCTIONS

    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.
    Argument:
    arg shoud point to a struct isdn_net_ioctl_cfg (defined in linux/isdn.h)
    Return:
    On success, the call returns 0. On failure, an error code is returned.
    IIOCNETGCF
    Get configurable parameters of an ISDN network interface.
    This call returns all ISDN related parameters of an interface.
    Argument:
    arg shoud point to a struct isdn_net_ioctl_cfg (defined in linux/isdn.h) which will be filled by the current setup.
    Return:
    On success, the call returns 0 and the interface-setup is copied to *arg. On failure, an error code is returned.
    IIOCNETANM
    Add a phone number to an ISDN network interface.
    This call adds a phone number to an existing network interface.
    Argument:
    arg shoud point to a struct isdn_net_ioctl_phone which contains necessary information.
    Return:
    On success, the call returns 0 and the phone number is added to either outgoing or incoming number list. On failure, an error code is returned.
    IIOCNETDNM
    Delete a phone number from an ISDN network interface.
    This call deletes a phone number from an existing network interface.
    Argument:
    arg shoud point to a struct isdn_net_ioctl_phone which contains necessary information.
    Return:
    On success, the call returns 0 and the phone number is deleted from either outgoing or incoming number list. On failure, an error code is returned.
    IIOCNETGNM
    Get list of phone numbers from an ISDN network interface.
    This call returns the list of phone numbers associated to an existing network interface.
    Argument:
    arg shoud point to a a union of struct isdn_net_ioctl_phone and a buffer, large enough to hold a concatenated list of strings containing the phone numbers.
    Return:
    On success, the call returns 0 and the list of phone numbers is returned as a space-separated list of number-strings terminated by a NULL byte.
    IIOCNETDIL
    Trigger dialing of an ISDN network interface.
    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 deafult.
    Argument:
    arg should point to a zero terminated string of max. 10 characters naming the desired interface.
    Return:
    On success, the call returns 0 and the interface starts dialing.

    This call initiates hangup of an ISDN network interface, if it is connected.
    Argument:
    arg should point to a zero terminated string of max. 10 characters naming the desired interface.
    Return:
    On success, the call returns 0 and the interface hangs up.
    IIOCNETALN
    Add a link of an MPP-configured ISDN network interface.
    This call initiates dialing of a Multilink-PPP slave ISDN network interface, if it is not connected.
    Argument:
    arg should point to a zero terminated string of max. 10 characters naming the desired interface.
    Return:
    On success, the call returns 0 and the interface starts dialing.
    IIOCNETDLN

    This call initiates hangup of an Multilink-PPP ISDN network interface, if it is connected.
    Argument:
    arg should point to a zero terminated string of max. 10 characters naming the desired interface.
    Return:
    On success, the call returns 0 and the interface hangs up.
    IIOCNETARU

    IIOCSETBRJ
    Set busreject flag of a lowlevel driver.
    Argument:
    arg should point to an struct isdn_ioctl_struct containing the driver's ID and the value of the busreject flag.

    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.
    Argument:
    none
    Return:
    This call always returns 0.
    IIOCGETPRF
    Get all modem register settings.
    With this call, all modem registers of all ttyI devices can be read.
    Argument:
    arg should point to a buffer of length ( ISDN_MODEM_ANZREG + ISDN_MSNLEN ) * ISDN_MAX_CHANNELS.
    Return:
    On return, the provided buffer is filled with the register values.
    IIOCSETPRF
    Set all modem register settings.
    With this call, all modem registers of all ttyI devices can be written.
    Argument:
    arg should point to a buffer of length ( ISDN_MODEM_ANZREG + ISDN_MSNLEN ) * ISDN_MAX_CHANNELS. filled with the values of all modem registers.
    Return:
    On return, the modem registers are set from the contents of the provided buffer.
    IIOCSETMAP
    Set Mapping table.
    This call is used to set 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 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.
