Andrey A. Chernov 3cfd1dbc21 Add new options:
-K: set keepalive SLIP timeout
-O: set outfill SLIP timeout
Handle SIGURG from keepalive like SIGHUP now, i.e. reconnect.
Back out background scription change, cause some synchro problems.

.Sh DESCRIPTION
.Pp
.Nm Startslip
opens the specified
.Ar device .
Once carrier is asserted (if modem control is enabled)
.Nm startslip
attempts to login as the specified
.Ar user
with the given
.Ar password .
Standard login: & Password: scheme assumed unless Annex option
specified (see
.Fl A ) .
If successful, it puts the device into the slip line discipline,
calls
.Ar upscript
and goes to wait mode.
If carrier drops (modem control enabled) or a
.Dv SIGHUP
is sent to
.Nm startslip ,
it closes the device, calls
.Ar downscript
and attempts to repeat the dialup and login sequence.
If a
.Dv SIGTERM
is send to
.Nm startslip ,
it closes the device, calls
.Ar downscript
and exits.
When
.Nm startslip
called twice on the same device, previous copy killed by a
.Dv SIGTERM
before any operation.
.Pp
Available options:
.Bl -tag -width Ar
.It Fl d
.Nm Startslip
prints out debugging information about what it is trying to do.
.It Fl b Ar speed
Determines the baud rate used for
.Ar device .
Default value is 9600.
.It Fl t Ar script_timeout
Set login script timeout in seconds, default value is 90.
.It Fl w Ar retry_pause
Set connecting retry pause in seconds (increased from one retry to another),
default value is 60.
.It Fl W Ar maxtries
Set maximum number of connection retries for one session,
default value is 6.
Value 0 means infinite count.
.It Fl s Ar string1
The optional
.Ar string
is written to
.Ar device .
Return character is added automatically.
For a dialup modem,
the string is used to specify a dial sequence.
Default string is return character.
You can specify several
.Fl s Ar stringN
arguments to use with each try, f.e. several host phone numbers.
.It Fl A Ar annexname
.Nm Startslip
assumes it is connecting to a Xylogics Annex box and engages in an
appropriate dialog using the
.Ar user
and
.Ar passwd
arguments.
The
.Ar annexname
argument is a string that is used to match against the Annex prompt
to determine when a connection has been established.
.It Fl h
Use hardware (CTS/RTS) flow control for
.Ar device .
Default value is no flow control.
.It Fl l
Disable modem control (waiting for carrier and carrier drop sense) for
.Ar device .
Modem control is enabled by default.
.It Fl U Ar upscript
Specifies a script to run when a SLIP interface becomes connected. This may
contain ifconfig, route, and other appropriate commands. The arguments that
are passed to the script are "slX up".
Default value is "/sbin/ifconfig".
Dial sequence number (see
.Fl s )
passed via
.Dv LINE
environment variable.
.It Fl D Ar downscript
Specifies a script to run when a SLIP connection goes away. The arguments that
are passed to the script are "slX down". Default value is "/sbin/ifconfig".
Dial sequence number (see
.Fl s )
passed via
.Dv LINE
environment variable.
.It Fl K Ar keepalive
Set SLIP "keep alive" timeout in seconds. If FRAME_END not received in this
timeout, reconnect occurse. Active "out fill" timeout expected from other
side.
Default value is no timeout.
.It Fl O Ar outfill
Set SLIP "out fill" timeout in seconds. It cause at least one FRAME_END
will be sended during this timeout.
Needed for "keep alive" timeout on other side.
Default value is no timeout.
