USB-RS232 adapter in FreeBSD 5?

[Bill Moran]

I've got a USB -> RS232 adapter I'm trying to get working on 5.3-RELEASE.

I've seen a lot of comments about these kind of things that seem to
indicate that they can be used (I occasionally have needs to use this
lappy as a serial console, and I'd like to use it to demonstrate a
serial barcode scanner that we have - normally, tip would work great
for this, but the laptop doesn't have a native RS-232 port).

Anyway, I get the impression that I'm missing some early, basic steps
to get this working.  dmesg shows:

ugen0: Prolific Technology Inc. USB-Serial Controller, rev 1.10/3.00, addr 2

But neither tip nor cu seems to talk to ugen0 very well.  Other posts
I've seen seem to indicate that I need to be talking to a ucom0 device,
but I see nothing like that in /dev.  Is there something missing from
my kernel?  I haven't been able to find any reference to ucom in the
GENERIC or NOTES files.

Any advice/pointers is welcome.

TIA.
