It has 4 16C550 serial <br /> ports a configurable locations (default 0x300, 0x308, <br /> 0x310, 0x318) with individual interrupts for each <br /> port. This works fine as individual ports. However I <br /> would like to get the IRQ sharing feature of the card <br /> working. For shared interrupts an additional register <br /> is available on the card (at 0x280, also <br /> configuratable).
