I think you are talking about LocalTalk.  That's a CSMA/CD usage of 
the port (like Ethernet) that runs at 230kbits/second.  Not supported 
by NetBSD at this time.

I suspect that the problem is what Greg Kritsch said really 
(interrupt handling) and stand corrected.  Since nobody seems to be 
using serial ports much there could be multiple problems I suppose.
