The following is the list of offending drivers, the ports that use them,
and the tty letters they use:

ttyv="%pc_chr%"				# amd64, arc, bebox, i386, prep, shark
if [ -z "$ttyv" ]
then
	ttyv="%physcon_chr%"		# acorn32, arm
fi
ttyA="%clcd_chr%"			# sparc, sparc64
if [ -z "$ttyA" ]
then
	ttyA="%zs_chr%"			# atari
fi

# alpha cesfic mac68k macppc mipsco mvme68k news68k newsmips next68k pmax
# sgimips sparc sparc64 sun2 sun3 x68k
ttyB="%zstty_chr%"
if [ -z "$ttyB" ]
then
	ttyB="%msc_chr%"		# amiga
	if [ -z "$ttyB" ]
	then
		ttyB="%ser_chr%"	# atari
	fi
fi
ttyZ="%zstty_chr%"
# acorn26 acorn32 algor alpha amd64 amiga arc arm atari bebox dreamcast
# evbmips evbppc hp300 hp700 hpcmips hpcsh i386 luna68k mac68k macppc
# news68k newsmips next68k playstation2 pmax pmppc prep sandpoint sgimips
# shark sparc sparc64 vax
ttyE="%wsdisplay_chr%"
# acorn26 acorn32 algor alpha amd64 amiga arc arm bebox cobalt dreamcast
# evbmips evbppc evbsh3 hp300 hp700 hpcmips hpcsh i386 ibmnws macppc mipsco
# mmeye mvmeppc pmppc prep sandpoint sgimips sh5 shark sparc sparc64
ttyC="%com_chr%"
ttyh="%sabtty_chr%"		# sparc, sparc64
ttyM="%dcm_chr%"		# hp300
ttya="%dcm_chr%"		# hp300

If we switch to use ptyfs, this really does not matter. On the other hand
it would be nice to cleanup the namespace.
