"An ActiveX component to access and control ISA I/O cards."
AXIO Control is an interesting and practical ActiveX component that has been created so the user can access and control ISA I/O cards based on Intel 8255A and 82C55A microcontrollers.
AXIO Control is also great because it`s very easy to use thanks to its intuitive interface which lets you simply interact between what you write and the hardware you want to control. For AXIO Control to work correctly you need to previously install Visual Basic Runtime 6.0 or later.
AXIO Control is totally free.
