That's hopefully fixed since 2.1 but for lack of feedback that
section hasn't been changed. Problem was that older versions of
NetBSD lost lots of interrupts on old world hardware which made the
serial ports pretty much unusable for anything more demanding than a
simple terminal session ( and everything else worked more or less by
accident only ). The interrupt code has seen major updates since then
and serial ports should be reliable now. I tested only up to
38400kBit/s because the machine on the other end wouldn't go faster -
not a single zmodem restart within hours, the machine was happily
processing a couple thousand interrupts per second.

Well, give it a shot and tell us.

I bought such an adaptor in a mac shop about 10 years ago. Bottom
line is you won't get hardware handshake but otherwise it works fine.
