I have modified init to call getty with the character put in /etc/ttys as
a speed labels (for the initial speed).  I include a patch below.  I
have not, however, managed to get the speed changes working.  I suspect
we need some changes in the tty driver to accomplish that.

I use Karl's (?) uucp port but have not tried dialing out.  The original
comments state that dialouts would not work because of missing hooks
in the tty driver.

Here is my gettydefs file (all speeds rotate bask to themselves)
Note that spaces around the speed characters (`f', `d', etc.)
are significant, i.e., do NOT put spaces around these characters.
