-.B local
-Don't use the modem control lines. With this option,
-.B pppd
-will ignore the state of the CD (Carrier Detect) signal from the modem and
-will not change the state of the DTR (Data Terminal Ready) signal.
-.TP
-.B mtu \fI<n>
-Set the MTU [Maximum Transmit Unit] value to \fI<n>\fR. Unless the
-peer requests a smaller value via MRU negotiation, \fIpppd\fR will
-request that the kernel networking code send data packets of no more
-than \fIn\fR bytes through the PPP network interface.
-.TP
-.B name \fI<n>
-Set the name of the local system for authentication purposes to <n>.
-.TP
-.B user \fI<u>
-Set the user name to use for authenticating this machine with the peer
-using PAP to <u>.
-.TP
-.B usehostname
-Enforce the use of the hostname as the name of the local system for
-authentication purposes (overrides the
-.B name
-option).
-.TP
-.B remotename \fI<n>
-Set the assumed name of the remote system for authentication purposes
-to <n>.
-.TP
-.B papcrypt
-Indicates that all secrets in the /etc/ppp/pap-secrets file which
-are used for checking the identity of the peer are encrypted, and thus
-pppd should not accept a password which (before encryption) is
-identical to the secret from the /etc/ppp/pap-secrets file.
-.TP
-.B proxyarp
-Add an entry to this system's ARP [Address Resolution Protocol] table
-with the IP address of the peer and the Ethernet address of this
-system.
-.TP
-.B \-proxyarp
-Disable the \fBproxyarp\fR option. The system administrator who
-wishes to prevent users from creating proxy ARP entries with
-\fIpppd\fR can do so by placing this option in the /etc/ppp/options
-file.
-.TP
-.B persist
-Do not exit after a connection is terminated; instead try to reopen
-the connection.
-.TP
-.B login
-Use the system password database for authenticating the peer using
-PAP.
-.TP
-.B noipdefault
-Disables the default behaviour when no local IP address is specified,
-which is to determine (if possible) the local IP address from the
-hostname. With this option, the peer will have to supply the local IP
-address during IPCP negotiation (unless it specified explicitly on the
-command line or in an options file).
-.TP
-.B lcp-echo-interval \fI<n>
-If this option is given, \fIpppd\fR will send an LCP echo-request
-frame to the peer every \fIn\fR seconds. Under Linux, the
-echo-request is sent when no packets have been received from the peer
-for \fIn\fR seconds. Normally the peer should respond to the
-echo-request by sending an echo-reply. This option can be used with
-the \fIlcp-echo-failure\fR option to detect that the peer is no longer
-connected.
