kimon is a simple ISDN monitor that attaches itself into the KDE taskbar. It displays the status of all connected ISDN devices that are known to ISDN4Linux. kimon can be configured to open a window with detailed information if a new connection is initiated via the ISDN devices. This program was designed to integrate the features of imon and isdnmon in the K Desktop Environment without using a lot of resources.

Kimon docked in the KDE 2 Panel.

Kimon ISDN channel monitor window.


The status of the different ISDN-channels are indicated by different colors. The color green indicates that the corresponding channel is not used. The colors red  and blue are representing outgoing and incoming calls.

If the symbol in the taskbar is double-clicked a monitor window is opened, where additional information on the connections can be found. If the right mouse-button is clicked a menu opens where the user can quit the program, open the monitor window or edit the options for kimon. A middle-click opens a user defined application i.e. xisdnload.

In the Preferences dialog the user can configure a lot of kimons properties. Most important are the paths to the isdninfo device (e.g. /dev/isdninfo) and the path to isdnctrl (e.g. /sbin/isdnctrl). Normally kimon just displays the phone number of the established connection, but it is possible to have a file in which phonenumbers and corresponding names are given. The format of the file (e.g. /etc/phonenumbers) is simple: Each line in this file has one phone number at the beginning of the line. After any number of whitespaces the name of the connection is given.

kimon can be configured to pop up the monitor window on outgoing or incoming calls, on both kinds of calls or never. If chosen in the preferences, the window closes automatically as well after any number of seconds. In the monitor window a lot of information is displayed to the user. The user can even terminate any connection by clicking on the colored light at the end of each line. If kimon has been started with the apropriate rights it issues an command to isdnctrl to terminate the connection.
