Enhancements: 1991 by David Orme

This update is provided by Brian Warris, ID 72500,3632.

My thanks to the aforementioned William Herrera and David Orme, who have created
a very good communications package.

My modifications are for the following reasons:
  1)  Port defs in comports.hpp for ports 3 and 4. My modem is on port 4, and
did not work correctly before.
  2)  Borland C++ 2.00 warnings. Everything now compiles with neither warning
nor error, and all warning flags are turned on in the make file.


Intended location for the files: (re: Borland C++ 2.00)
