Obviously I am terrible at explaining things as I never seem to be able 
to get people to understand what I am trying to do with this app.  I 
find it very simple, but I must be leaving out important info.  Let me 
try drawing an ASCII art picture...
  Test Fixture      Forth App     Terminal Emulator
   +--------+       +--------+       +---------+
   |        | RS232 | Forth  |  ???  |  RS232  |
   |  UUT   |<=====>|  User  |<=====>|   Data  |
   |        |       |  I/O   |       | Display |
   +--------+       +--------+       +---------+

The middle box is the Forth app with its own console I/O.  The left box 
is a test fixture connected to the computer by RS-232.  The user 
controls the app through the console I/O and when actually production 
testing boards test results are copied into the paste buffer by the 
program to be pasted into a spread sheet.

The current iteration of the program uses a socket connection to display 
the RS232 message data in a terminal emulator as a second window 
separate from the console.  This is useful as a debug tool but is not 
strictly required for production testing.

Just to be clear, the rPi will not be used for production testing.  If 
possible I would like to have a single source file which will compile 
correctly on both Linux and Windows systems, but that is not essential 
and not even important at this stage.  Right now I'd just like to get 
the serial port working and find a way to display the traffic data 
somewhere other than the console window.  I think the pipes thing may 
work just fine, possibly under Windows as well.
