Deflate scheme, with a maximum window size of \fI2**nr\fR bytes, and
agree to compress packets sent to the peer with a maximum window size
of \fI2**nt\fR bytes. 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
+the value given for \fInr\fR. Values in the range 9 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
and as the default name to send to the peer when authenticating itself
to the peer. This option is privileged.

+.B dryrun
+With the \fBdryrun\fR option, pppd will print out all the option
+values which have been set and then exit, after parsing the command
+line and options files and checking the option values, but before
+initiating the link. The option values are logged at level info, and
+also printed to standard output unless the device on standard output
+is the device that pppd would be using to communicate with the peer.
+.TP
+.B dump
+With the \fBdump\fR option, pppd will print out all the option values
+which have been set. This option is like the \fBdryrun\fR option
+except that pppd proceeds as normal rather than exiting.

.B endpoint \fI<epdisc>
Sets the endpoint discriminator sent by the local machine to the peer
during multilink negotiation to \fI<epdisc>\fR. The default is to use

.B kdebug \fIn
Enable debugging code in the kernel-level PPP driver. The argument
-\fIn\fR is a number which is the sum of the following values: 1 to
+values depend on the specific kernel driver, but in general a value of
+1 will enable general kernel debug messages. (Note that these
+messages are usually only useful for debugging the kernel driver
+itself.) For the Linux 2.2.x kernel driver, the value is a sum of
+bits: 1 to
enable general debug messages, 2 to request that the contents of
received packets be printed, and 4 to request that the contents of
transmitted packets be printed. On most systems, messages printed by
.B nocrtscts
Disable hardware flow control (i.e. RTS/CTS) on the serial port.
If neither the \fIcrtscts\fR nor the \fInocrtscts\fR nor the
-\fIcdtrcts\fR nor the \fInodtrcts\fR option is given, the hardware
+\fIcdtrcts\fR nor the \fInocdtrcts\fR option is given, the hardware
flow control setting for the serial port is left unchanged.

-.B nodtrcts
+.B nocdtrcts
This option is a synonym for \fInocrtscts\fR. Either of these options will
disable both forms of hardware flow control.
