Hi Bob. Thanx for the clarification. What is a cascade interrupt. I have
always been puzzled by this. For some programs setting COM3 to IRQ2 does
the same thing - makes my device communicate with the computer. I have
never fully understood why this is so and why specifying one or the
other interrupt works some times and not other.
To beat an old phrase to death: "Curious minds want to know."
