Subject: DL-11 defined in /dev/MAKEDEV plus change to dh.4 man page (#74)
Index:	/dev/MAKEDEV,/usr/src/man/man4/dh.4 2.11BSD

Description:
	The 11/93 and 11/94 have 7 extra DL-11 type serial ports on the
	cpu board.  A device node name was needed.  'dl' was selected
	and the /dev name is /dev/ttyl[1-7].  Unit 0 is reserved for the
	console device.

Repeat-By:
	Put 2.11BSD on a 11/93, note that /dev/MAKEDEV doesn't know what
	to do.

Fix:
	It is highly unlikely that more than 4 DH-11 units will (or can)
	be used.  The dh.4 man page and /dev/MAKEDEV script were updated 
	to only allow tty[h,i,j,k] and ttyl was selected as the DL-11
	device name.
