    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
