isdnmonitor -- isdn4bsd / isdnd remote monitoring tool
isdnmonitor [-c] [-d debuglevel] [-f filename] [-h hostspec] [-l pathname] [-p portspec]
isdnmonitor is used to remotely monitor the operation of the ISDN demon, isdnd(8), which
manages all ISDN related connection and disconnection of ISDN devices supported by the
The options are as follows:
-c Switch to (curses-) fullscreen mode of operation. In this mode, isdnmonitor behaves
nearly exactly as isdnd(8) in fullscreen mode. In fullscreen mode, entering the con-
trol character Control-L causes the display to be refreshed and entering
Carriage-Return or Enter will pop-up a command window. Because isdnmonitor will not
listen to messages while the command window is active, this command window will dis-
appear automatically after 5 seconds without any command key press.
While the command window is active, Tab or Space advances to the next menu item. To
execute a command, press Return or Enter for the highlighted menu item, or enter the
number corresponding to the item to be executed or enter the capitalized character

displaying debug messages on the full-screen display.
-f Specifying this option causes isdnmonitor to write its normal output and - if

-l is used to specify a Unix local domain socket name to be used for communication
between isdnd(8) and isdnmonitor
-h is used to specify a hostname or a dotted-quad IP address of a machine where an
isdnd(8) is running which should be monitored.
-p This option may be used to specify a remote port number in conjunction with the -h
The following environment variables affect the execution of isdnmonitor:
TERM The terminal type when running in full-screen display mode. See environ(7) for more
For a first try, the following command should be used to start isdnmonitor to monitor a
locally running isdnd:
isdnmonitor -h localhost
Exit status is 0 on success, 1 on error.
