modem control is enabled) -.Nm -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 , -it closes the device, calls -.Ar downscript -and attempts to repeat the dialup and login sequence. -If a -.Dv SIGTERM -is send to -.Nm , -it closes the device, calls -.Ar downscript -and exits. -When -.Nm -called twice on the same device, previous copy killed by a -.Dv SIGTERM -before any operation. -.Pp -The following options are available: -.Bl -tag -width indent -.It Fl d -Print out debugging information. -.It Fl b Ar speed -Determine 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 stringN -The optional -.Ar stringN -is written to -.Ar device . -Return character is added automatically. -For a dialup modem, -the string is used to specify a dial sequence. -No string written by default. -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 -The -.Nm -utility assumes it is connecting to a Xylogics Annex box and engages in an -appropriate dialog using the -.Ar user -and -.Ar password -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 -Specify a script to run when a SLIP interface becomes connected. -This may -contain -.Xr ifconfig 8 , -.Xr route 8 , -and other appropriate commands. -The arguments that -are passed to the script are "slX up". -Default value is -.Pa /sbin/ifconfig . -Dial sequence number (see -.Fl s ) -passed via -.Ev LINE -environment variable. -.It Fl D Ar downscript -Specify a script to run when a SLIP connection goes away. -The arguments that -are passed to the script are "slX down". -Default value is -.Pa /sbin/ifconfig . -Dial sequence number (see -.Fl s ) -passed via -.Ev LINE -environment variable. -.It Fl K Ar keepalive -Set SLIP "keep alive" timeout in seconds. -If FRAME_END not received during this -time period, a reconnect will occur. -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 causes at least one FRAME_END -to be sent during this timeout. -Needed for "keep alive" timeout on other side. -Default value is no timeout. -.It Fl S Ar unit -Set SLIP unit number directly. -Use with caution, no check for two -interfaces with same number made. -Default is dynamic assignment. -.It Fl L -Use uucp-style device locking. -You need it unless you start -.Nm -from external program which already does uucp locking. -Default case is no uucp locking to satisfy such programs. -.El -.Sh FILES -.Bl -tag -width
