     ttrrsspp - transliterate sequenced packet protocol trace

     Trpt interrogates the buffer of SPP trace records created when a socket
     is marked for ``debugging'' (see setsockopt(2)),  and prints a readable
     description of these records.  When no options are supplied, ttrrsspp prints
     all the trace records found in the system grouped according to SPP con-
     nection protocol control block (PCB). The following options may be used
     to alter this behavior.

     --aa      In addition to the normal output, print the values of the source
             and destination addresses for each packet recorded.

     --jj      Just give a list of the protocol control block addresses for
             which there are trace records.

     --pp      Show only trace records associated with the protocol control
             block at the given address, _h_e_x_-_a_d_d_r_e_s_s.

     --ss      in addition to the normal output, print a detailed description of
             the packet sequencing information.

     --tt      in addition to the normal output, print the values for all timers
             at each point in the trace,

     The recommended use of ttrrsspp is as follows.  Isolate the problem and en-
     able debugging on the socket(s) involved in the connection.  Find the ad-
     dress of the protocol control blocks associated with the sockets using
     the --AA option to netstat(1).  Then run ttrrsspp with the --pp option, supplying
     the associated protocol control block addresses.  If there are many sock-
     ets using the debugging option, the --jj option may be useful in checking
     to see if any trace records are present for the socket in question.

     If debugging is being performed on a system or core file other than the
     default, the last two arguments may be used to supplant the defaults.

     Should also print the data for each input or output, but this is not
     saved in the race record.

     The output format is inscrutable and should be described here.
