-- I modified the original HyperFinger to learn how it worked.  In
-- the process, I untangled and streamlined the code.  One no longer
-- needs to be a codehead to understand it.  Enjoy.

-- -- The XCMDs and XFCNs used here are:
-- -- TCPNameToAddr, TCPSend, TCPRecvUpTo, TCPState, TCPRelease, TCPClose,
-- -- and TCPPassiveOpen by Harry Chesley © 1989 Apple Computer, Inc.
