TTY minor device numbers

[C. Harald Koch]

What is the difference between the ttyd*, ttym*, and ttyf* devices? What do
the various bits in the minor device number really do?

>From scouring the manuals, I have managed to find that ttym* is meant for
modems, which probably means that an open() call won't return until DCD is
set. I can't find anything else, other than an obscure reference to the
Owner's Guide (which doesn't say anything useful).
