Hi,

Just to be sure, this is what we want for speakup_dummy.

1. register ldisc structure in spk_tty_probe().
2. in spk_tty_probe(), attach line discipline - like you would for
/dev/ttyX from user space
3. in open() method of ldisc structure, take the tty_struct and cache it.
4. in spk_serial_out_tty() call tty->ops->write() instead of outb().

What have a I missed here?

Thanks,
Okash
