  Normally, \fBpppd\fR requires a terminal device. With this option, \fBpppd\fR
! allocates itself a pseudo-tty master/slave pair and uses the slave as its
  terminal device. \fBpppd\fR creates a child process to act as a character shunt
! to transfer characters between the pseudo-tty master and its standard input and
! output. Thus, \fBpppd\fR transmits characters on its standard output and
! receives characters on its standard input even if they are not terminal
  devices. This option increases the latency and CPU overhead of transferring
  data over the ppp interface as all of the characters sent and received must
  flow through the character shunt process. An explicit device name may not be
  given if this option is used.

  Specifies that the command \fIscript\fR, and not a specific terminal device is
! used for serial communication. \fBpppd\fR allocates itself a pseudo-tty
! master/slave pair and uses the slave as its terminal device. \fIscript\fR runs
! in a child process with the pseudo-tty master as its standard input and output.
! An explicit device name may not be given if this option is used. (Note: if the
! \fBrecord\fR option is used in conjunction with the \fBpty\fR option, the child
! process will have pipes on its standard input and output.)

  Directs \fBpppd\fR to record all characters sent and received to a file named
  \fIfilename\fR. \fIfilename\fR is opened in append mode, using the user's
! user-ID and permissions. Because this option uses a pseudo-tty and a process to
! transfer characters between the pseudo-tty and the real serial device, it
! increases the latency and CPU overhead of transferring data over the PPP
! interface. Characters are stored in a tagged format with timestamps that can be
! displayed in readable form using the \fBpppdump\fR(1M) program. This option is
! generally used when debugging the kernel portion of \fBpppd\fR (especially CCP
! compression algorithms) and not for debugging link configuration problems. See
! the \fBdebug\fR option.
