Yes the Kernel looks at the $i for the device you login on. it then
looks in the DEVICE file for a $I that matches, unless you are logging
in from a virtual terminal like a telnet or DECserver then it looks
for a match on the part of the $I in the DEVICE file. That's why you
don't have to have every /dev/tty device in the DEVICE file.
For instance, /dev/tty1, /dev/tty2,.../dev/tty100 can all be handled
by one DEVICE record with a $I of /dev/tty and a terminal type of
VIRTUAL TERMINAL. Otherwise you would need one entry for each of
these devices with a terminal type of C-VT102.
Once the Device is Determined by the $I then the kernel checks the
TERMINAL type to get the characteristics of that TERMINAL TYPE like,
page width and length, how to make bold letters, how to make the font
size change and all of the other fields in the terminal Type file.
I don't know if I answered your question or danced around it, but I do
think that the Kernel systems manual (?) is the document that you
want, it is the big kernel manual anyway. I think it has a seperate
section on devices and terminal types.
