freebsd stable - Dec 2004 - ucom and sio

Judging from the man page, ucom is limited to acting like a tty with no
support for sio. Is this true? Is there some magic config bit somewhere
that will enable hidden sio support?

I have some old software that talks to some old hardware over rs232 (using
cuaa) and the builtin 232 port just died. I'm trying to get a Bafo BF-810
working in raw mode but haven't had much luck (open()'s and
write()'s
block, unless non-blocking is set, but then they return without doing
anything).

Any suggestions?

Thanks

Ummm, I don't know what you are asking here.  ucom supports all the
rs232 stuff w/o problem.  I use it all the time with my phone to dial
into the network.
