what happened to /etc/ttytypes?

[Undergrad Projects Lab]

Hi all!

I was looking in my manual recently.  The manual that I have is for the 3.51 OS.
and the tset(1) info makes reference to /etc/ttytypes(5) for which I can find 
neither an actual file nor a page in my manuals.

Am I missing something from my manuals, or is it just not there?  Does anyone
have the format that this file is _supposed_ to take?  I've looked on other 
unix systems that I have access to.  On the three systems I've looked on, none
of them have an /etc/ttytypes file.  The tset(1) man page does note that this
version of tset is for the AT&T Unix PC only, which leads me to believe that
other unix systems would not have the /etc/ttytypes file on them.

I can kludge my way around the use of this file, but it's not as elegant as
I'd like.  If anyone could tell me the format of this file, and/or whether or
not it really makes a difference, it would be appreciated.

Thanks again for all your wonderful assistance!!!

P.P.S.	Hey, kls at ditka, I didn't put a garbage "Followup-To:" line in this
	post.  However, I don't understand why that was a bad thing to do.
