Add -t to specify login script timeout. Add -w to specify retry wait time. Describe -p option. Now understand several -s sections (for several host phone numbers). Remove -F sw (software flow control), it is impossible with slip. Change -F hw (hardware flow control) option to -h as in slattach, we don't need option with argument for only one case. Call downscript on SIGTERM. Improve debug diagnostic. Allow startslip work with several slip lines without killing each other. Unlink pid file on exit. Skip \r and \0 in login script parsing instead making them \n. Use absolute path to default script (/sbin/ifconfig). Call up/down script in background to prevent hang on them.

|
opens the specified

|
|
.Pp
|
|
Once carrier is asserted
|
|
.Nm startslip
|
|
attempts to login as the specified
|
|
.Ar user
|
|
with the given

If carrier drops or a
|
|
.Dv SIGHUP
|
|
is sent to
|
|
.Nm startslip ,
|
|
it closes the device, calls

|
|
and attempts to repeat the dialup and login sequence.
|
|
If a
|
|
.Dv SIGTERM
|

is send to
|
|
.Nm startslip ,
|

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 passwd
|
|
arguments.
|
|
