|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
tool implements the Q.2110 transport protocol.
|
|
Normally the program reads from standard input and sends this input over
|
|
the SSCOP protocol on the standard output file descriptor. This means, that
|
|
the standard output file descriptor should be connected in read-write mode.
|
|
The program takes the
|
|
following arguments:
|
|
.Bl -tag -width ".It Fl a Ar p Ns Li = Ns Ar v"
|
|
.It Fl F
|
|
Use frameing on the SSCOP connection (see the
|
|
.Fl f
|
|
option).
|
|
.It Fl V Ar X
|
|
Set the verbose flag to the hex value
|
|
.Ar X .
|
|
.It Fl W Ar N
|
|
Set the initial SSCOP window to
|
|
.Ar N .
|
|
.It Fl a Ar p Ns Li = Ns Ar v
|
|
Set SSCOP parameter
|
|
.Ar p
|
|
to the value
|
|
.Ar v .
|
|
The following parameters may be set:
|
|
.Bl -tag -width ".It Li stat Ns = Ns Ar N"
|
|
.It Li j Ns = Ns Ar N
|
|
Set the maximum SSCOP-UU data size to
|
|
.Ar N
|
|
octets.
|
|
.It Li k Ns = Ns Ar N
|
|
Set the maximum SSCOP SDU data size to
|
|
.Ar N
|
|
octets.
|
|
.It Li cc Ns = Ns Ar N
|
|
Set the parameter
|
|
.Li MaxCC
|
|
(maximum number of connection control message re-transmissions) to
|
|
the value
|
|
.Ar N .
|
|
.It Li pd Ns = Ns Ar N
|
|
Set the parameter
|
|
.Li MaxPD
|
|
(maximum acceptable number of outstanding unacknowledged SD PDUs before
|
|
sending a POLL) to the value
|
|
.Ar N .
|
|
.It Li stat Ns = Ns Ar N
|
|
Set the parameter
|
|
.Li MaxSTAT
|
|
(maximum number of elements placed in a STAT PDU) to the value
|
|
.Ar N .
|
|
.El
|
|
.It Fl b
|
|
Enable the ATM-Forum SSCOP robustness enhancement.
|
|
.It Fl e
|
|
Exit when there is an end of file condition on the input file or the
|
|
SSCOP indicates a release confirmation.
|
|
.It Fl f
|
|
Use the framing protocol for communication over the SSCOP link. See
|
|
.Xr frame l
|
|
(libbegemot) for framing.
|
|
.It Fl h
|
|
Print a short help information and exit.
|
|
.It Fl i
|
|
Try not to read from the user input file descriptor. Assume that we a receiving
|
|
only.
|
|
.It Fl l Ar N
|
|
Loose every Nth message. This is used for testing.
|
|
.It Fl r
|
|
Revert user and SSCOP file descriptors. That means, that user input and output
|
|
is done on standard output and SSCOP input and output on standard input.
|
|
.It Fl t Ar t Ns Li = Ns Ar m
|
|
Set SSCOP timer
|
|
.Ar t
|
|
to
|
|
.Ar m
|
|
milliseconds. The following timers may be set:
|
|
.Bl -tag -width ".It Li stat Ns = Ns Ar N"
|
|
.It Li cc Ns = Ns Ar m
|
|
Set the connection control timer to
|
|
.Ar m .
|
|
This timer controls the retransmission of connection control messages.
|
|
.It Li poll Ns = Ns Ar m
|
|
Set the poll timer to
|
|
.Ar m .
|
|
This timer controls the transmission of POLL messages.
|
|
.It Li ka Ns = Ns Ar m
|
|
Set the keep-alive timer to
|
|
.Ar m .
|
|
This timer controls the maximum length of the transient phase.
|
|
.It Li nr Ns = Ns Ar m
|
|
Set the no-response timer to
|
|
.Ar m .
|
|
This timer controls the maximum time between two received STAT PDUs before
|
|
the connection is aborted.
|
|
.It Li idle Ns = Ns Ar m
|
|
Set the idle timer to
|
|
.Ar m .
|
|
This timer controls the length of the idle phase.
|
|
.El
|
|
.It Fl v Ar X
|
|
Set the SSCOP library verbose flag to the hex value.
|
|
.It Fl w
|
|
Don't start the SSCOP protocol. Wait for a establish indication from the remote
|
|
side.
|
|
.It Fl x
|
|
Enable to POLL after retransmission flag.
|
|
.It Fl 3
|
|
Send user output to file descriptor 3.
|
|
.El
|
|
.Sh EXAMPLES
|
|
The following command line sends the file
|
|
.Pa Makefile
|
|
over a pipe (this depends on the feature that pipes are bi-directional):
|
|
.Bd -literal
|
|
cat Makefile | sscop -reF | sscop -weF
|
|
.Ed

|
|
.Sh STANDARDS
|
|
The implemented protocol conforms to ITU-T recommendation Q.2110.
