.Sh NAME
.Nm isdntest
.Nd isdn4bsd debugging and verification tool
.Sh SYNOPSIS
.Nm
.Op Fl c Ar unit
.Op Fl d Ar level
.Op Fl i Ar number
.Op Fl h
.Op Fl o Ar number
.Op Fl t Ar num
.Op Fl w
.Sh DESCRIPTION
The
.Nm
utility is part of the isdn4bsd package and may be used as a stimulation tool
for debugging the isdn4bsd kernel functionality.
.Pp
NOTE:
The
.Nm
utility must be run
.Em instead
of the
.Xr isdnd 8
daemon and cannot be used while the daemon runs.
.Pp
The following options are available:
.Bl -tag -width Ds
.It Fl c
Use controller unit number for test.
.It Fl d
Set the debugging level
.It Fl h
Use HDLC as the B channel layer 1 protocol instead of no protocol.
.It Fl i
Use number to verify the incoming number.
.It Fl o
Use number as the outgoing number to dial.
.It Fl t
Set number of times the test pattern on the B-channel is exchanged
.It Fl w
Wait for keyboard input for terminating the call.
.El
.Pp
The
.Nm
utility is currently of not much use for end users, it is primarily a debugging
tool for development and is part of the release in the hope, that someone
enhances it as a real self test and setup-verification tool!
.Pp
The
.Nm
utility does almost no error checking and error recovery, so unexpected
hangs or crashes may occur.
.Sh EXAMPLES
For the following example, it is assumed that a machine with isdn4bsd
installed is connected to an S0 bus and that one of the valid MSN's (MSN = Multiple Subscriber Number
= telephone number) on this bus is
.Em 42 .
The
.Xr isdnd 8
.Em must
not currently running on that machine!
Executing:
.Bd -literal -offset indent
isdntest -i 42 -o 42
.Ed
.Pp
will setup an outgoing call from that machine to itself, connect to itself
and disconnect after 5 seconds.
The
.Nm
utility has to be finished by the user by entering Control-C.
