Brad, Well I won't claim to be an expert on the *BSD OSs, but I had the same problem when I first brought up NetBSD. I had gone in and configured com 0-3 like I would normally for xenix and linux, IRQ 4 for both com0 and com2 and IRQ 3 for both com1 and com3. I didn't get my serial ports to work until I dropped support for com2 and com3. My cheap-o serial cards had limited IRQ configurations available. It appears the com drivers have problems supporting multiple com ports on the same IRQ. I could very well be wrong, but the serial ports on my installation of NetBSD 0.9 wouldn't work until I unconfigured com3 and com4. The only support I have for this is that all of the configuration files in the conf dir have all the com ports on different IRQs and my experience. If any one knows better, please correct me as I would like all 4 of my com ports working.
