|
|
.Sh SYNOPSIS
|
|
.Cd device \&"i4b\&"
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
device driver is used by the
|
|
.Xr isdnd 8
|
|
daemon to exchange messages with the isdn4bsd kernel part for the purpose
|
|
of call establishment, control and disconnection and to access various
|
|
control and status informations.
|
|
The
|
|
.Nm
|
|
device can only be opened by a single process and is not meant to be used
|
|
by user programs.
|
|
.Pp
|
|
The messages and message parameters are documented in the include
|
|
file
|
|
.Em /usr/include/machine/i4b_ioctl.h .
|
|
.Pp
|
|
The most important available ioctl's are:
|
|
.Pp
|
|
.Bl -tag -width Ds -compact -offset indent
|
|
.It Ar I4B_CDID_REQ
|
|
Request a unique Call Description IDentifier (cdid) which identifies
|
|
uniquely a single interaction of the local D channel with the exchange.
|
|
.It Ar I4B_CONNECT_REQ
|
|
Actively request a call setup to a remote ISDN subscriber.

|
|
Request information about an installed ISDN controller card.
|
|
.It Ar I4B_DIALOUT_RESP
|
|
Give information about call setup to driver who requested dialing out.
|
|
.It Ar I4B_TIMEOUT_UPD
|
|
Update the kernels timeout value(s) in case of dynamically calculated
|
|
shorthold mode timing changes.
|
|
.It Ar I4B_UPDOWN_IND
|
|
Inform the kernel userland drivers about interface soft up/down status
|
|
changes.
|
|
.It Ar I4B_CTRL_DOWNLOAD

|
Download firmware to active card(s).
|
|
.It Ar I4B_ACTIVE_DIAGNOSTIC
|

An incoming call from a remote ISDN user is indicated.
|
|
.It Ar MSG_CONNECT_ACTIVE_IND
|
|
After an incoming call has been accepted locally or an outgoing call has

.It Ar MSG_DISCONNECT_IND

A call was terminated.
|
|
.It Ar MSG_DIALOUT_IND
