! 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.
