A DH is not a DHV; the drivers are no doubt completely different.
To get eight bit output, set LITOUT mode:

	int set = LLITOUT;

	/* what is the `official' type for the third arg to ioctl? */
	/* I think it has changed several times now... */
	if (ioctl(fd, TIOCLBIS, &set))
		/* gripe */

The driver bugs, which certainly *should* be fixed in Ultrix 1.2,
may be surmounted by re-asserting the baud rate:

	struct sgttyb sg;

	if (ioctl(fd, TIOCGETP, &sg) || ioctl(fd, TIOCSETP, &sg))
		/* gripe */
