Forgive me, I have only basic C knowledge.

I could see that UCOM_CDEV_MAJOR is fixed to 138, but I can see 
no reference to the minor address. 

Can you give me a hint what the print statement could look like?


ucom_attach(struct ucom_softc *sc)
{
        struct tty *tp;
        int unit;

        unit = device_get_unit(sc->sc_dev);

        sc->sc_tty = tp = ttymalloc(sc->sc_tty);
        tp->t_oproc = ucomstart;
        tp->t_param = ucomparam;
        tp->t_stop = ucomstop;

        DPRINTF(("ucom_attach: tty_attach tp = %p\n", tp));

        DPRINTF(("ucom_attach: make_dev: ucom%d\n", unit));

        sc->dev = make_dev(&ucom_cdevsw, unit | UCOM_CALLOUT_MASK,
                        UID_UUCP, GID_DIALER, 0660,
                        "ucom%d", unit);
        sc->dev->si_tty = tp;

        return (0);
}
