I did look at that as an example; it looks like to me you don't
need to do anything extra with the com driver to enable interrupts
for status changes (or perhaps the com driver does that all of the
time). So I could easily believe that this is broken for people on
Sparc hardware that has the old serial port hardware.

Well, I modified the code, compiled, and...nothing. No change in behavior.


Actually, there is a change, it's worse. Without the modification, ntpd opens the port using PPS and I'm able to start gpsd right behind it once PPS is active. With the modification, I can't use the port at all after PPS takes over, it just keeps gpsd locked out.
