I was trying to add a terminal to my MINIX system the other night.  I hooked up
the terminal (an adm3a-alike) to /dev/tty2.  Then I looked at /etc/ttys.  It
contains one line: "100".  I looked in the AST book, and all I found was a line
about the fact that /etc/ttys contains one line per terminal attached to the
system.  Yeah, thanks, I knew that.  I looked for "init" in the book, so I
could maybe find the place where it reads /etc/ttys and forks.  No such luck;
init doesn't appear (at least anywhere I could find in 20 minutes) in the book.
So I mounted my source-code partition and dug through the code with elvis.  I
found that the second entry should be "1fx" where f is the code for 9600/8/N
and x is the line number.

My question is this: should this number be a '1' or a '2'?  Init subtracts a
'0' from it to get the line number, so it is unclear whether /dev/tty2 is
line 1 (counting from 0) or 2 (counting from 1).  I tried both a '1' and a '2'
in this position, but neither worked (I think it was my cable, actually), and
I am going to try again tonight with a new (null-modem) cable.

Anybody got any tips as to what the /etc/ttys entry ought to be?

advTHANKSance,
