   3 Test TCP connection.  Makes a connection on port 5001
   4 and transfers fabricated buffers or data copied from stdin.

   6 Usable on 4.2, 4.3, and 4.1a systems by defining one of
   7 BSD42 BSD43 (BSD41a)
   8 Machines using System V with BSD sockets should define SYSV.

  14      catch SIGPIPE to be able to print stats when receiver has died
  15      for tcp, don't look for sentinel during reads to allow small transfers
  16      increased default buffer size to 8K, nbuf to 2K to transfer 16MB
  17      moved default port to 5001, beyond IPPORT_USERRESERVED
  18      make sinkmode default because it is more popular,
  19              -s now means don't sink/source
  20      count number of read/write system calls to see effects of
  21              blocking from full socket buffers
  22      for tcp, -D option turns off buffered writes (sets TCP_NODELAY sockopt)
  23      buffer alignment options, -A and -O
  24      print stats in a format that's a bit easier to use with grep & awk
  25      for SYSV, mimic BSD routines to use most of the existing timing code

  27      -b sets the socket buffer size (SO_SNDBUF/SO_RCVBUF)

  30 Modified Oct. 1991 at Silicon Graphics, Inc.
  31      use getopt(3) for option processing, add -f and -T options.
  32      SGI IRIX 3.3 and 4.0 releases don't need #define SYSV.
