.Sh DESCRIPTION
This program provides command line control of the
.Nm ppp
.Xr ppp 8
daemon. Its primary use is to facilitate simple scripts that
control a running daemon.
.Nm Pppctl
expects at least two arguments. The first is interpreted as the
socket on which the
is passed at least one argument, specifying the socket on which
.Nm ppp
daemon is listening. If the socket contains a leading '/', it
is taken as an AF_LOCAL socket. If it contains a colon, it is
treated as a host:port pair, otherwise it is treated as just a
port specification on the local machine (127.0.0.1). Both the
host and port may be specified numerically if you wish to avoid
a DNS lookup or don't have an entry for the given port in
is listening. Refer to the
.Sq set server
command of
.Nm ppp
for details. If the socket contains a leading '/', it
is taken as an
.Dv AF_LOCAL
socket. If it contains a colon, it is treated as a
.Ar host:port
pair, otherwise it is treated as a TCP port specification on the
local machine (127.0.0.1). Both the
.Ar host
and
.Ar port
may be specified numerically if you wish to avoid a DNS lookup
or don't have an entry for the given port in
.Pa /etc/services .

All remaining arguments are concatenated to form the

Don't forget to escape or quote the ';' as it is a special character
for most shells.
If no
.Ar command
arguments are given,
.Nm
enters interactive mode, where commands are read from standard input.
When in interactive mode, the
.Fl v
option is assumed. Any password negotiation due to the
.Fl p
option is done prior to enabling the
.Fl v
option.
The following command line options are available:
