But this driver is 100% broken. It should have been removed in 8.0 time
frame. There's nothing here to 'deprecate' more to just delete something
that Ed forgot to remove a decade ago...  We had a bunch of of other tty
drivers that we retired around the same time because nobody stepped up to
bringing them forward...  This one looks to be forgotten...
