Our guess is that we're losing due to dropped interrupts due to the IRQ sharing (ie, we think that at high traffic levels even heroic attempts by the sio driver can't keep us from being hosed by the wretched ISA bus design). So we're looking for a new multi-port serial board that doesn't need IRQ sharing, ie, one with a co-processor. Does anybody have any recommendations for (or against) any of the co-processor based multi-port serial boards supported in recent releases of FreeBSD? Thanks! --Rob Austein
