This is a simple port i/o utility written in LabWindows/CVI 5.5.  It
does not require installation of the DriverLINX Port I/O driver.

It is ideal for users who are programming CVI with our ISA I/O mapped PIO cards or
the KPCI-3160 or KPCI-PDISO8A or KPCI-PIO32IOA I/O mapped PCI cards.  However, this
example is not specific to any particular board product.  It just accesses
I/O space of the computer.  Knowledge of the board product's register map
is required to customize the program to carry out a particular task.  For example,
PIO cards based upon the Intel 8255 chip have a typical register map of:

base addr = Port A
base + 1  = Port B
base + 2  = Port C
base = 3  = Control Register


Just run the Setup to install the Run-Time version.  The GUI is 
modeled on our "port95nt.exe" utility that runs in Microsoft VB or C++.
