.Sh DESCRIPTION
|
|
.Nm
|
|
is part of the isdn4bsd package and is used to control the level of
|
|
debugging output of the isdn4bsd kernel part.
|
|
Every layer of the isdn4bsd kernel uses a debugging mask which can be
|
|
manipulated using this utility.
|
|
.Pp
|
|
A second usage of
|
|
.Nm
|
|
is to display and reset chipset specific statistics and/or error counters
|
|
and and to display and reset the D-channel layer 2
|
|
(Q.921 LAPD protocol) statistics and error counters.
|
|
.Pp
|
|
The following options are available:
|
|
.Bl -tag -width Ds
|
|
.It Fl c
|
|
Display chipset specific statistics and/or error counters.
|
|
.It Fl e
|
|
Set debugging mask for the selected layer(s) to display errors only.
|
|
.It Fl g
|
|
Get the debugging mask for the selected layer(s).
|
|
.It Fl l
|
|
Specify the layer for which a command applies. Default is all layers.
|
|
.It Fl m
|
|
Set debugging mask for the selected layer(s) to display all possible
|
|
debugging messages (maximum output).
|
|
.It Fl q
|
|
Display the Q.921 (D-channel layer 2) frame receive/transmit statistics.
|
|
.It Fl r
|
|
Set debugging mask for the selected layer(s) to the compiled in default
|
|
(reset).
|
|
.It Fl s
|
|
Set debugging mask for the selected layer(s) to value. Value can be
|
|
specified in any number base supported by
|
|
.Xr sscanf 3 .
|
|
.It Fl u
|
|
Set the unit numbers for the -c, -q, -C and -Q flags.
|
|
.It Fl z
|
|
Set debugging mask for the selected layer(s) to no output at all (zero).
|
|
.It Fl H
|
|
Reset the chipset specific statistics and/or error counters to zero.
|
|
.It Fl Q
|
|
Reset the Q.921 (D-channel layer 2) frame receive/transmit statistics to zero.
