SUMMARY:

This is a simple hardware port diagnostic program that will allow you to
transmit 8-bit data (00 to FF) to any hardware port (0000 to FFFF).  This 
could become a valuable tool when troubleshooting or testing PC based 
projects, digital circuits or PC cards since this program also 
allows you to toggle the data bits with the function keys (F5 to F12).  You
can also use the up/down arrow keys to increment/decrement the data being
sent to the port.

This version fixes some port addressing bugs and fixed a problem with data 
transmition when misc. keys were pressed.  The program outputs only after a
data value has been entered.
