-.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.
+.B ipx-network \fI<n>
+Set the IPX network number in the IPXCP configure request frame to
+<n>. There is no valid default. If this option is not specified then
+the network number is obtained from the peer. If the peer does not
+have the network number, the IPX protocol will not be started. This is
+a hexadecimal number and is entered without any leading sequence such
+as 0x. It is related to the \fIipxcp-accept-network\fR option.
+.TP
+.B ipx-node \fI<n>:<m>
+Set the IPX node numbers. The two node numbers are separated from each
+other with a colon character. The first number <n> is the local node
+number. The second number <m> is the peer's node number. Each node number
+is a hexadecimal number, to the maximum of ten significant digits. The
+node numbers on the ipx-network must be unique. There is no valid
+default. If this option is not specified then the node number is
+obtained from the peer. This option is a related to the
+\fIipxcp-accept-local\fR and \fIipxcp-accept-remote\fR options.
+.TP
+.B ipx-router-name \fI<string>
+Set the name of the router. This is a string and is sent to the peer
+as information data.
+.TP
+.B ipx-routing \fI<n>
+Set the routing protocol to be received by this option. More than one
+instance of \fIipx-routing\fR may be specified. The '\fInone\fR'
+option (0) may be specified as the only instance of ipx-routing. The
+values may be \fI0\fR for \fINONE\fR, \fI2\fR for \fIRIP/SAP\fR, and
+\fI4\fR for \fINLSP\fR.
+.TP
+.B ipxcp-accept-local
+Accept the peer's NAK for the node number specified in the ipx-node
+option. If a node number was specified, and non-zero, the default is
+to insist that the value be used. If you include this option then you
+will permit the peer to override the entry of the node number.
+.TP
+.B ipxcp-accept-network
+Accept the peer's NAK for the network number specified in the
+ipx-network option. If a network number was specified, and non-zero, the
+default is to insist that the value be used. If you include this
+option then you will permit the peer to override the entry of the node
+number.
+.TP
+.B ipxcp-accept-remote
+Use the peer's network number specified in the configure request
+frame. If a node number was specified for the peer and this option was
+not specified, the peer will be forced to use the value which you have
+specified.
+.TP
+.B ipxcp-max-configure \fI<n>
+Set the maximum number of IPXCP configure request frames which the
+system will send to <n>. The default is 10.
+.TP
+.B ipxcp-max-failure \fI<n>
+Set the maximum number of IPXCP NAK frames which the local system will
+send before it rejects the options. The default value is 3.
+.TP
+.B ipxcp-max-terminate \fI<n>
+Set the maximum nuber of IPXCP terminate request frames before the
+local system considers that the peer is not listening to them. The
+default value is 3.
