The debugging level is the sum of the +following values: +.Pp +.Bl -tag -width Ds -compact -offset indent +.It Ar 0x001 +general debugging. +.It Ar 0x002 +rates calculation. +.It Ar 0x004 +timing calculations. +.It Ar 0x008 +state transitions. +.It Ar 0x010 +retry handling. +.It Ar 0x020 +dialing. +.It Ar 0x040 +process handling. +.It Ar 0x080 +isdn4bsd kernel i/o calls. +.It Ar 0x100 +controller and channel busy/free messages. +.El +.Pp +The value can be specified in any number base supported by the +.Xr sscanf 3 +library routine. +.Pp +In addition, this option accepts also the character 'n' as an argument to +disable displaying debug messages on the full-screen display. +.Pp +.It Fl f +Specifying this option causes +.Nm isdnd +to enter the full-screen mode of operation. When operating in this mode, +entering the control character +.Em Control-L +causes the display to be refreshed and entering +.Em Carriage-Return +or +.Em Enter +will pop-up a command window. Because the +.Nm +daemon will not listen to messages while the command window is active, +this command window will disappear automatically after 5 seconds without +any command key press. +.Pp +While the command window is active, +.Em Tab +or +.Em Space +advances to the next menu item. To execute a command, press +.Em Return +or +.Em Enter +for the highlighted menu item, or enter the number corresponding to the +item to be executed or enter the capitalized character in the menu item +description. +.It Fl l +If this option is set, logging is not done via the +.Xr syslogd 8 +facility but instead is appended to a file. +.It Fl L +Specifies the name of the logfile which is used when the option +.Em -l +is set. +.It Fl P +This option prints out the parsed and verified isdnd configuration in the same +format as the isdnd.rc file. This output can be used as an isdnd.rc file. This +feature is especially useful when debugging an isdnd.rc file to see, what the +default settings of options are when they are not set in the isdnd.rc input +file. +.Pp +The +.Nm +exits after the printout is done. +.It Fl F +This option prevents +.Nm isdnd +to detach from the controlling tty and become a daemon. +.It Fl r +In conjunction with the +.Fl t +option, +.Ar device +specifies a terminal device which becomes the controlling tty for +.Nm isdnd +and on which the full-screen mode output is displayed. +.It Fl s +This option may be used to specify the logging facility in case +.Xr syslog 3 +logging is configured and another facility than the default LOCAL0 +facility shall be used. The facility is to be specified as an integer in +the range 0-11 or 16-23 (see the file /usr/include/syslog.h). +.It Fl t +In conjunction with the +.Fl f +and +.Fl r +options, +.Ar terminaltype +specifies a terminal type or termcap entry name (such as vt220) for the device +used for +.Nm isdnd +full-screen output. This is useful if an unused (no getty running) tty line is +used for full-screen output for which no +.Li TERM +environment variable exists. +.It Fl u +Specifies the length of a charging unit in case the config file entry +keyword +.Em unitlenghtsrc +is set to +.Em cmdl . +.It Fl m +If the isdn daemon is compiled with local or remote monitoring support, +this option disables all monitoring access. It overrides the config +file option +.Em monitor-allowed . +.El +.Pp +.Sh INTERACTION WITH THE KERNEL +.Nm Isdnd +communicates with the kernel part of isdn4bsd by receiving status and +event messages ( +.Xr read 2 +from device /dev/i4b ) and by transmitting commands and responses ( +.Xr ioctl 2 +from device /dev/i4b ). +.Pp +The messages and message parameters are documented in the include +file +.Em /usr/include/machine/i4b_ioctl.h . +.Pp +Supported command and response messages (ioctl's) to the kernel are: +.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. +.It Ar I4B_CONNECT_RESP +Respond to an incoming call, either accept, reject or ignore it. +.It Ar I4B_DISCONNECT_REQ +Actively terminate a connection. +.It Ar I4B_CTRL_INFO_REQ +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 +Return diagnostic information from active cards. +.El +.Pp +.Pp +Supported status and event messages from the kernel are: +.Bl -tag -width Ds -compact -offset indent +.It Ar MSG_CONNECT_IND +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 +been accepted by a remote, the exchange signaled an active connection +and the corresponding B-channel is switched through. +.It Ar MSG_DISCONNECT_IND +A call was terminated. +.It Ar MSG_DIALOUT_IND +A userland interface driver requests the daemon to dial out (typically a +network interface when a packet arrives in its send queue). +.It Ar MSG_IDLE_TIMEOUT_IND +A call was terminated by the isdn4bsd kernel driver because a B-channel +idle timeout occurred. +.It Ar MSG_ACCT_IND +Accounting information from a network driver. +.It Ar MSG_CHARGING_IND +Charging information from the kernel. +.El +.Pp +.Ss OUTGOING CALLS +Currently the only possibility to trigger an outgoing call is that an +isdn4bsd network driver +.Em (ipr<n>) +sends a +.Em MSG_DIALOUT_IND +to the +.Nm +daemon. +.Pp +The daemon requests a new CDID from the kernel by using the +.Em I4B_CDID_REQ +ioctl message, this CDID is now used in all interactions with the kernel +to identify this single call until a disconnect occurs. +.Pp +After getting the CDID, the daemon looks up several additional information +in its entry section of the configuration corresponding to that connection +and issues a +.Em I4B_CONNECT_REQ +ioctl message to the kernel. The kernel now dials the remote side and +if the remote side accepts the call, the kernel sends a +.Em MSG_CONNECT_ACTIVE_IND +to the daemon. +.Pp +The call is terminated by either the local site timing out or the remote +side hanging up the connection or the local side actively sending a +.Em DISCONNECT_REQ +ioctl message, both events are signaled to the +.Nm +by the kernel sending the +.Em DISCONNECT_IND +message and the CDID corresponding to the call is no longer valid. +.Pp +.Ss INCOMING CALLS +Incoming calls are signaled to the +.Nm +by the kernel transmitting the +.Em MSG_CONNECT_IND +message to the daemon. +.Pp +With the information contained in this message, the +.Nm +searches the entry section of its configuration database and if a match is +found, it accepts or rejects the call or, of no match is found, it ignores the +call - all by issuing a +.Em I4B_CONNECT_RESP +ioctl message with the appropriate parameters to the kernel. +.Pp +In case the daemon decided to accept the message, the kernel signal the then +active connection by sending a +.Em MSG_CONNECT_ACTIVE_IND +message to the daemon. +.Pp +The call is terminated by either the local site timing out or the remote +side hanging up the connection or the local side actively sending a +.Em DISCONNECT_REQ +ioctl message, both events are signaled to the +.Nm +by the kernel sending the +.Em DISCONNECT_IND +message and the CDID corresponding to the call is no longer valid. +.Pp + +.Sh SIGNALS + +Sending a HUP signal to +.Nm +causes all open connections to be terminated and the configuration file is +reread. In case aliasfile handling was enabled, the aliasfile is also +reread. + +Sending a USR1 signal to +.Nm +causes the accounting file and the logfile (if logging to a file is used +instead of logging via the +.Xr syslog 3 +facility) to be closed and reopened to make logfile rotation possible. + +.Sh ENVIRONMENT +The following environment variables affect the execution of +.Nm isdnd : +.Bl -tag -width Ds +.It Ev TERM +The terminal type when running in full-screen display mode. +See +.Xr environ 7 +for more information. +.El + +.Sh FILES +.Bl -tag -width /etc/isdn/isdnd.rates -compact +.It Pa /dev/i4b +The device-file used to communicate with the kernel ISDN driver subsystem. + +.It Pa /var/log/messages +A record of the actions in case of syslogd logging support. + +.It Pa /var/log/isdnd.acct +The default accounting information filename (if accounting is configured). + +.It Pa /var/log/isdnd.log +The default logging filename (if logging to a file is configured). + +.It Pa /var/run/isdnd.pid +The process id of the isdn daemon (also known as "lockfile" to isdnd, preventing multiple invocations of it). + +.It Pa /usr/local/lib/isdn +.It Pa /etc/isdn +The directory where isdnd expects some supplementary data files and programs +for telephone answering support. + +.It Pa /etc/isdn/isdnd.rc +The default runtime configuration file. + +.It Pa /etc/isdn/isdnd.rates +The default unit charging rates specification file. + +.It Pa /etc/isdn/isdntel.alias +The default table (if aliasing is enabled) to convert phone number to caller's name. +.El + +.Sh EXAMPLES +For a first try, the following command should be used to start +.Nm +in foreground mode for better debugging the configuration setup: +.Bd -literal -offset indent +isdnd -d0xf9 -F +.Ed +.Pp +This will start isdnd with reasonable debugging settings and produce +output on the current terminal. +.Nm Isdnd +can then be terminated by entering Control-C. +.Pp +Another example, the command: +.Bd -literal -offset indent +isdnd -d0xf9 -f -r /dev/ttyv3 -t vt100 +.Ed +.Pp +will start +.Nm isdnd +with reasonable debugging messages enabled, full-screen mode of operation, +full-screen display redirected to /dev/ttyv03 and using a termcap entry +for vt100 on this display. + +.Sh DIAGNOSTICS +Exit status is 0 on success, 1 on error. +.Pp + +.Sh SEE ALSO +.Xr syslogd 8 , +.Xr isdntrace 8 , +.Xr isdntel 8 , +.Xr isdnd.rc 5 , +.Xr isdnd.rates 5 , +.Xr i4bisppp 4 , +.Xr i4bipr 4 + +.Sh BUGS +Still one or more left. + +.Sh AUTHOR +The +.Nm +daemon and this manual page were written by Hellmuth Michaelis.

This should +allow you to run any national isdn protocol delivered by EICON.Diehl +for your card, but the driver has only been tested with the DSS1 +protocol and some parts of the cards interface are isdn protocol +dependend. +.Pp +The +.Nm +driver is written to conform to the software interface documented +by Diehl in their +.Nm ISDN-Karten Benutzerhandbuch +from 1992. +.Sh MICROCODE DOWNLOAD +Every active card needs its own operating software before it can +work. You have to download this to the card before using it with +ISDN4BSD. Use the isdnctl utility to do this, i.e. call +.Nm "isdnctl -d te_etsi.sx 1" +to download the file +.Nm te_etsi.sx +to controller number 1. Use +.Nm "isdnctl -l" +to list all available controllers (and ports). You have to select the +correct isdn protocol file for your isdn interface, see the Diehl documentation +for details. +.Pp +The cards bootstrap process involves another file, which is independend +of the card type you use and the protocol you run. It is called +.Nm download.bin +in current versions of the Diehl software distribution and has to be +copied to the kernel compile directory under +.Nm dev/ic/microcode/daic +and converted into a header file used when compiling the kernel by running +.Nm make +in that directory. Your kernel compile will fail and remind you of this +if you forget to do this. Due to copright restrictions we cannot distribute +the driver with this file integrated. But if you own a card, you do have +the file (or can get it from the Diehl web server). +.Sh BUGS +The driver is not yet finished. It will only compile on NetBSD and +even there will not work. This should be fixed soon and the driver +will be ported to FreeBSD. +.Sh SEE ALSO +.Xr isdnctl 1 diff --git a/usr.sbin/i4b/man/i4b.4 b/usr.sbin/i4b/man/i4b.4 new file mode 100644 index 0000000..f285c08 --- /dev/null +++ b/usr.sbin/i4b/man/i4b.4 @@ -0,0 +1,108 @@ +.\" +.\" Copyright (c) 1997, 1998 Hellmuth Michaelis.
