dc(4) has the restrictions.  it doesn't look like dz(4) does, though,
and I don't find any attachments for dc(4) in vax configuration files,
even though the dc(4) manual page mentions the VAXstation 2000 and 3100.
(should I file a PR?)

$ find . -type f -name files.\* | xargs grep -E '^(device|attach).*\<dc\>'
./pmax/conf/files.pmax:device dc: tty
./pmax/conf/files.pmax:attach dc at ibus with dc_ds

$ find . -type f -name files.\* | xargs grep -E '^(device|attach).*\<dz\>'
./vax/conf/files.vax:attach     dz at vsbus with dz_vsbus
./vax/conf/files.vax:attach     lkkbd at dz with dzkbd
./vax/conf/files.vax:attach     lkms at dz with dzms

maybe dc was used with vaxen in the past, but it looks like dz is used
now.

maybe andrew or ragge can shed some light.
