Does anyone understand why COM 2 and 4 is sharing @ IRQ 3? That makes no sense to me. Because if you have two serial connections, one at COM 2 and the other @ COM 4, then you have an IRQ conflict @ IRQ 3.
All in all, why not just add another IRQ for COM 3 and COM 4 so that there are not as many IRQ conflict problems?
