+/*
+ * T T C P . C
+ *
+ * Test TCP connection. Makes a connection on port 5001
+ * 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
