-/*
- *        T T C P . C
- *
- * Test TCP connection.  Makes a connection on port 5010
- * and transfers fabricated buffers or data copied from stdin.
- *
- * Usable on 4.2, 4.3, and 4.1a systems by defining one of
- * BSD42 BSD43 (BSD41a)
- * Machines using System V with BSD sockets should define SYSV.
- *
- * Modified for operation under 4.2BSD, 18 Dec 84
- *       T.C. Slattery, USNA
- * Minor improvements, Mike Muuss and Terry Slattery, 16-Oct-85.
- * Modified in 1989 at Silicon Graphics, Inc.
- *        catch SIGPIPE to be able to print stats when receiver has died 
- *        for tcp, don't look for sentinel during reads to allow small transfers
- *        increased default buffer size to 8K, nbuf to 2K to transfer 16MB
- *        moved default port to 5001, beyond IPPORT_USERRESERVED
- *        make sinkmode default because it is more popular, 
- *                -s now means don't sink/source 
- *        count number of read/write system calls to see effects of 
- *                blocking from full socket buffers
- *        for tcp, -D option turns off buffered writes (sets TCP_NODELAY sockopt)
- *        buffer alignment options, -A and -O
- *        print stats in a format that's a bit easier to use with grep & awk
- *        for SYSV, mimic BSD routines to use most of the existing timing code
- * Modified by Steve Miller of the University of Maryland, College Park
- *        -b sets the socket buffer size (SO_SNDBUF/SO_RCVBUF)
- * Modified Sept. 1989 at Silicon Graphics, Inc.
- *        restored -s sense at request of tcs@brl
- * Modified Oct. 1991 at Silicon Graphics, Inc.
- *        use getopt(3) for option processing, add -f and -T options.
- *        SGI IRIX 3.3 and 4.0 releases don't need #define SYSV.
- *
- * Modified --> Nov 1996 at CERN (Daniel DAVIDS)
- *        printout of the Socket-Buffer-Sizes 
- *        configured for HP-UX 9000 OS        
- *        configured for Windows NT OS 
- * Modified Dec 1996 at CERN (Jacques ROCHEZ)
- *        severe cleanup
- *        addaptation to the gcc compiler (ANSI)
- *        configured for Lynx OS 
- *        automatic format for the rate display (G/M/K/)bytes/sec
- *        added log (L) and more help (h) options.
- * Modified May 1997 at CERN (Jacques ROCHEZ) 
- *        removed the mes() function following err() function.
- *        changed the default port to 5010
- * Modified jul 1997 at CERN (Jacques ROCHEZ)
- *        adapted the timing calculation in microseconds 
- *        addapted the code for Vsisual C++ under NT4.0 
- * Modified aug 1997 at CERN (Jacques ROCHEZ)
- *        initialise to 0 the variables nbytes, numcalls  
- *        moved the buffer pre-load outside the measured timed area 
- * Distribution Status -
- *        Public Domain.  Distribution Unlimited.
- * Modified jun 1998 at Epigram
- *        - print hash marks to indicate prograss on transmitting side
- *        - sleep between bursts of buffers
- *        - set number of buffers/burst
- * Modified jul 1998 at Epigram
- *        - send random size buffers
- * Modified jan 1999 at Epigram (WES)
- *        - added start and end patterns to UDP start and end packets
- *        - added handling of missed start, end, or data packets for UDP tests
