Port Configuration:
Each eight-bit port can be configured as inputs or outputs. The API provides a
set adapter state call to access the control words.
Note: The control panel also allows you to configure the device. Your program
can over ride the control panel configuration when executed, but the control
panel configuration will be the default on power up. The default settings are
based on the settings in the control panel application when last changed and
saved after re-booting.
