+.B modem
+Use the modem control lines. This option is the default. With this
+option,
+.B pppd
+will wait for the CD (Carrier Detect) signal from the modem to be asserted
+when opening the serial device
+(unless a connect script is specified), and it will drop the DTR (Data
+Terminal Ready) signal briefly when the connection is terminated and before
+executing the connect script.
+On Ultrix, this option implies hardware
+flow control, as for the \fBcrtscts\fR option.
+.TP
+.B ms-dns \fI<addr>
+If
+.I pppd
+is acting as a server for Microsoft Windows clients, this option
+allows
+.I pppd
+to supply one or two DNS (Domain Name Server) addresses to the
+clients. The first instance of this option specifies the primary DNS
+address; the second instance (if given) specifies the secondary DNS
+address.
+.TP
+.B name \fI<n>
+Set the name of the local system for authentication purposes to <n>.
+.TP
+.B netmask \fI<n>
+Set the interface netmask to <n>, a 32 bit netmask in "decimal dot"
+notation (e.g. 255.255.255.0). If this option is given, the value
+specified is ORed with the default netmask. The default netmask is
+chosen based on the negotiated remote IP address; it is the
+appropriate network mask for the class of the remote IP address, ORed
+with the netmasks for any non point-to-point network interfaces in the
+system which are on the same network.
+.TP
+.B noaccomp
+Disable Address/Control compression in both directions (send and
+receive).
+.TP
+.B nobsdcomp
+Disables BSD-Compress compression; \fBpppd\fR will not request or
+agree to compress packets using the BSD-Compress scheme.
+.TP
+.B noccp
+Disable CCP (Compression Control Protocol) negotiation. This option
+should only be required if the peer is buggy and gets confused by
+requests from
+.I pppd
+for CCP negotiation.
+.TP
+.B nocrtscts
+Disable hardware flow control (i.e. RTS/CTS) on the serial port. If
+neither the \fBcrtscts\fR nor the \fB\-crtscts\fR option is given,
+the hardware flow control setting for the serial port is left
+unchanged.
+.TP
+.B nodefaultroute
+Disable the \fBdefaultroute\fR option. The system administrator who
+wishes to prevent users from creating default routes with \fIpppd\fR
+can do so by placing this option in the /etc/ppp/options file.
+.TP
+.B nodeflate
+Disables Deflate compression; \fBpppd\fR will not request or agree to
+compress packets using the Deflate scheme.
+.TP
+.B nodetach
+Don't detach from the controlling terminal. Without this option,
+if a serial device other than its controlling terminal is specified,
+.I pppd
+will fork to become a background process.
+.TP
+.B noip
+Disable IPCP negotiation and IP communication. This option should
+only be required if the peer is buggy and gets confused by requests
+from
+.I pppd
+for IPCP negotiation.
+.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 noipx
+Disable the IPXCP and IPX protocols. This option should only be
+required if the peer is buggy and gets confused by requests from
+.I pppd
+for IPXCP negotiation.
+.TP
+.B nomagic
+Disable magic number negotiation. With this option,
+.I pppd
+cannot detect a looped-back line. This option should only be needed
+if the peer is buggy.
+.TP
+.B nopcomp
+Disable protocol field compression negotiation in both the receive and
+the transmit direction.
+.TP
+.B nopredictor1
+Do not accept or agree to Predictor-1 comprssion.
+.TP
+.B noproxyarp
+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 novj
+Disable Van Jacobson style TCP/IP header compression in both the
+transmit and the receive direction.
+.TP
+.B novjccomp
+Disable the connection-ID compression option in Van Jacobson style
+TCP/IP header compression. With this option, \fIpppd\fR will not omit
+the connection-ID byte from Van Jacobson compressed TCP/IP headers,
+nor ask the peer to do so.
+.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.
