Note that currently we don't add the DBDMA properties at the end of the reg property because QEMU doesn't yet support serial DBDMA, but perhaps it is time to start turning on DBDMA logging to see if this is what's is causing OT to get stuck.
In fact, do we know if OT ever worked on MOL at all or did it provide its own drivers?
In any case, MOL has a comment /* this hack keeps MacOS 9 happy */ just above the point where it enables serial DBDMA on ch-b, so that sounds like a rather big hint for us. I might go try this now..
Interesting. Does MOL implement full emulation or does it manage to persuade OS 9 to not crash by fudging some properties? And thinking about it, does MOL use OT for its networking emulation or does it use its own drivers?
