I'm using a converter based on the FTDI232BM, on
ucom0: FTDI USB to Serial Cable, rev 1.10/4.00, addr 2
I am seeing the ucom0 work with normal input/output,
but not with getty. With getting it prompts for the
login then, upon hitting return, freezes. Without
getty I can send and receive characters all day long
without problems. Once the freeze happens, I can stty
-f ucom0 -hup and data starts again.

Perhaps, at least on one count.

I'm happy for you. I've been using FreeBSD since it
was called 386BSD + patches and there are many things
I've never had problems with too. It seems we're both
happy people... mostly.

That's precisely the area I'm interested in.

I don't want to effect change, I just want a working
system. If you're serious about supporting an
operating system you have to support all your uses,
even the assholes.
