.B +chap
Require the peer to authenticate itself using CHAP [Cryptographic
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 deflate \fInr,nt
+Request that the peer compress packets that it sends, using the
+Deflate scheme, with a maximum window size of \fI2**nr\fR bits, and
+agree to compress packets sent to the peer with a maximum window size of
+\fI2**nt\fR bits. If \fInt\fR is not specified, it defaults to the value
+given for \fInr\fR. Values in the range 8 to 15 may be used for
+\fInr\fR and \fInt\fR; larger values give better compression but
+consume more kernel memory for compression dictionaries.
+Alternatively, a value of 0 for \fInr\fR or \fInt\fR disables
+compression in the corresponding direction. (Note: \fBpppd\fR
+requests Deflate compression in preference to BSD-Compress
+if the peer can do either.)
+.TP
+.B \-deflate
+Disables Deflate compression; \fBpppd\fR will not request or agree to
+compress packets using the Deflate scheme.
+.TP
+.B demand
+Initiate the link only on demand, i.e. when data traffic is present.
+With this option, the remote IP address must be specific by the user
+on the command line or in an options file. \fBpppd\fR will initially
+configure the interface and enable it for IP traffic without
+connecting to the peer. When traffic is available, \fBpppd\fR will
+connect to the peer and perform negotiation, authentication, etc.
+When this is completed, \fBpppd\fR will commence passing data packets
+(i.e., IP packets) across the link. The persist, idle and holdoff
+options are often useful in conjuction with this option.

fully qualified domain name is porsche.Quotron.COM, you would use the
domain option to set the domain name to Quotron.COM.
.TP
+.B holdoff \fI<n>
+Specifies how many seconds to wait before re-initiating the link after
+it terminates. This option only has effect if the persist option is
+used.
+.TP
+.B idle \fI<n>
+Specifies that \fBpppd\fR should disconnect if it is idle for
+\fI<n>\fR seconds. The link is idle when no data packets (i.e. IP
+packets) are being sent or received.
+.TP
.B -ip
Disable IPCP negotiation and IP communication. This option should
only be required if the peer is buggy and gets confused by requests
