DHU-11 driver for 4.2BSD

[Chris Torek]

Two quick things I noticed:

If you want this to coexist with a dh, change

	int cbase[MAXNUBA];

to

	static int cbase[MAXNUBA];

Also, you have propagated a bug from the dh driver; dhuioctl
should check

		if (cmd == TIOCSETP || cmd == TIOCSETN || cmd == TIOCLSET ||
		    cmd == TIOCLBIS || cmd == TIOCLBIC)

instead of just the first two, before calling dhuparam.
