#
# Device "make" file.  Valid arguments:
#	all	makes all known devices, standard number of units (or close)
#	std	standard devices
#	local	configuration specific devices
#
# Tapes:
#	wt*	QIC-interfaced (e.g. not SCSI) 3M cartridge tape
#	st*	"NEW type scsi tapes" (old driver uses the
#		block devices of the disks to get access)
#
# Disks:
#	wd*	"winchester" disk drives (ST506,IDE,ESDI,RLL,...)
#	fd*	"floppy" disk drives (3 1/2", 5 1/4")
#	as*	"SCSI" disk/tape/CDROM drives
#	sd*	"NEW type scsi disks"
#	cd*	"NEW type cdrom disks"
#
# Console ports:
#	pc*	devices for stock pccons
#	vty*	virtual console devices for syscons/pcvt/codrv
# 
# Terminal ports:
#	com*	standard PC COM ports (really makes tty* entries for com)
#	sio*	fast interrupt PC COM ports (really makes tty* entries for sio)
#	tty*	alias for sio ports, this is what the system really wants
#
# Pseudo terminals:
#	pty*	set of 16 master and slave pseudo terminals
#	vty*	virtual terminals using syscons/pcvt/codrv console
#
# Printers:
#	lpt*	stock lp
#	lpa*	interruptless lp
#
# Call units:
#
# Special purpose devices:
#	bpf*	packet filter
#	dcf*	dcf clock
#	speaker	pc speaker
#	tw*	xten power controller
