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);
}
bye
