.Sh NAME
|
|
.Nm slattach
|
|
.Nd attach serial lines as network interfaces
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl Hhlmn
|
|
.Op Fl s Ar baudrate
|
|
.Op Fl t Ar ldisc
|
|
.Ar ttyname
|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
is used to assign a tty line to a network interface which uses asynchronous
|
|
serial lines.
|
|
.Pp
|
|
Currently the
|
|
.Nm
|
|
command is used to attach
|
|
.Xr sl 4
|
|
or
|
|
.Xr strip 4
|
|
interfaces.
|
|
These interfaces have to be created using the
|
|
.Xr ifconfig 8
|
|
.Cm create
|
|
subcommand before the
|
|
.Nm
|
|
command.
|
|
The network source and destination addresses and other interface parameters
|
|
are configured via
|
|
.Xr ifconfig 8 .
|
|
.Pp
|
|
The following operands are supported by
|
|
.Nm :
|
|
.Bl -tag -width Ar
|
|
.It Fl H
|
|
Turn on DTR/CTS flow control.
|
|
By default, no flow control is done.
|
|
.It Fl h
|
|
Turn on RTS/CTS flow control.
|
|
By default, no flow control is done.
|
|
.It Fl l
|
|
Turn on the CLOCAL flag, making it possible to run SLIP on a cable
|
|
without modem control signals (e.g. DTR, DSR, DCD).
|
|
.It Fl m
|
|
Maintain modem control signals after closing the line.
|
|
Specifically, this disables HUPCL.
|
|
.It Fl n
|
|
Don't detach from invoking tty.
|
|
.It Fl s Ar baudrate
|
|
Specifies the speed of the connection.
|
|
If not specified, the default of 9600 is used.
|
|
.It Fl t Ar ldisc
|
|
Specifies the line discipline to use for the tty.
|
|
Supported line disciplines are
|
|
.Dq slip
|
|
(creates a
|
|
.Xr sl 4
|
|
instance) and
|
|
.Dq strip
|
|
(creates a
|
|
.Xr strip 4
|
|
instance).
|
|
If this option is not specified, the default is
|
|
.Dq slip .
|
|
.It Ar ttyname
|
|
Specifies the name of the tty device.
|
|
.Ar ttyname
|
|
should be a string of the form
|
|
.Ql ttyXX ,
|
|
or
|
|
.Ql /dev/ttyXX .
|
|
.El
|
|
.Pp
|
|
Only the super-user may attach a network interface.
|
|
.Pp
|
|
To detach the interface, use
|
|
.Dq Li ifconfig interface-name down
|
|
after killing off the
|
|
.Nm
|
|
process.
|
|
.Ar Interface-name
|
|
is the name that is shown by
|
|
.Xr netstat 1 .
|
|
.Sh EXAMPLES
|
|
.Bd -literal -offset indent -compact
|
|
slattach ttyh8
|
|
slattach \-s 4800 /dev/tty01
|
|
.Ed
|
|
.Sh DIAGNOSTICS
|
|
Messages indicating that the specified interface is not configured or created,
|
|
the requested address is unknown, or that the user is not privileged
|
|
but tried to alter an interface's configuration.

.Sh HISTORY
|
|
The
|
|
.Nm
|
|
command appeared in
|
|
.Bx 4.3 .
|
|
.Sh BUGS
|
|
There is no way to specify the interface name (sl%d etc.) to be attached by the
|
|
.Nm
|
|
command.
|
|
There is no way to see which interface is assigned to the specified tty by the
|
|
.Nm
|
|
command, either.
|
|
.Pp
|
|
It would be better if the network interfaces were created by the
|
|
.Nm
|
|
command rather than by using the
|
|
.Xr ifconfig 8
|
|
.Cm create
|
|
subcommand before the
|
|
.Nm
|
|
command.
