: 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.


   This sounds exactly like my problem...  lll give it a shot and let everyone
   know tomorrow!

: Good Luck,

   Thanks I need it.
