Yep. Some of them are notorious for sometimes losing the first couple
of bytes of the transaction and we - like many other programs - don't
recover from that particularly well.

I've never fully characterized kernel/driver/hardware versions of the
2303 combianation that are terrible, but I *have* convinced myself that
at least one 2303 product (the one donated to the project by Alan) would
not under reliably transfer data to the host under any OS I tried it
on.

Oddly, I've seen some 2303's work rock solid under Linux and some that.
won't. I've tried, but I'll be darned if I can figure out the pattern.

That page seems about a half bubble off level to me, but I guess fixing
that is a different project...
