       pppdump - convert PPP record file to readable format


       pppdump [ -h | -p [ -d ]] [ -r ] [ -m mru ] [ file ...  ]


       The  pppdump utility converts the files written using the record option
       of pppd into a human-readable format.  If one  or  more  filenames  are
       specified,  pppdump  will read each in turn; otherwise it will read its
       standard input.  In each case the result is written to standard output.

       The options are as follows:

       -h     Prints  the  bytes sent and received in hexadecimal.  If neither
              this option nor the  -p  option  is  specified,  the  bytes  are
              printed as the characters themselves, with non-printing and non-
              ASCII characters printed as escape sequences.

       -p     Collects  the  bytes  sent  and  received  into   PPP   packets,
              interpreting  the  async  HDLC framing and escape characters and
              checking the FCS (frame check sequence)  of  each  packet.   The
              packets  are  printed  as  hex  values  and  as characters (non-
              printable characters are printed as ‘.’).

       -d     With the -p option, this option  causes  pppdump  to  decompress
              packets  which  have  been  compressed  with the BSD-Compress or
              Deflate methods.

       -r     Reverses the direction indicators, so that ‘sent’ is printed for
              bytes  or  packets  received, and ‘rcvd’ is printed for bytes or
              packets sent.

       -m mru Use mru as the MRU (maximum receive unit) for both directions of
              the  link when checking for over-length PPP packets (with the -p
