So to get the >16 port support, I download the source from the snapshot
area and build cygwin1.dll myself? Or can I just get prebuilt version
from the snapshot tree?

Sorry for the dumb questions. I've been using and loving cygwin for
a while now and have built things as complex as an ARM7 toolchain
and custom GDB debug stub for the target, but I've never poked around
cygwin itself since it pretty much "just works"

The serial port issue is the first major issue I've not been able
to work around easily, so far.

Cheers, Ralph
