Yes, but it seems that you didn't care about changes we have made locally 
or brought in from other BSD's? I just checked quickly the change I 
remember doing for sure - 

So, before it goes in, it should be _very_ carefully audited, please.

And please stay away from USB serial stuff while going to sync device 
drivers. These are in much better shape in DragonFly than in FreeBSD. I 
wouldn't mind at all (no, I'd love to see that, really) if someone would 
sync ucom(4) itself with FreeBSD, but it would require to merge changes 
from tty(4) as well I'm not familiar at all.

It's a diff between synchronized DragonFly (ie. the first patch applied) 
and FreeBSD current?

Good work, anyway.
