This example makes use of two drivers:

1.  DriverLINX for KPCMCIA
2.  DLPortIO driver for reading/writing to the I/O Registers of the 
    card.  This is a 32bit Port I/O driver.

The three ports of the card will initialize as inputs.

To make them output ports, the DriverLINX implementation for
the KPCMCIA-PIO24-C requires the use of the DriverLINX Configuration
Panel (see web site FAQ for procedure).  The DriverLINX driver
does not provide a means to do it from the code.

This example uses the DLPortIO driver to directly access the 
registers of the card to configure Port B for output direction.
Port B is used to control the relays of the ERA-01.

The same concepts can be implemented for the other ports of the
card at base address+0 (Port A) and base address+2 (Port C).
