I'm not sure I fully understand what you're trying to do here, but
youcan login to a linux box with a terminal just by connecting it
to a serial port and running a getty on that line with /etc/inittab.
See the T0 and T1 lines in your own inittab for an example.

Obviously you then have to login to telnet out, and you don't tell
us why you don't want to do that. I would have thought it's more
secure to have to login. (Just like not putting it into
/etc/securetty.)

I don't understand what you mean about connecting serial ports
together. I shouldn't do that in any hardware sense.

Then you say you want to have a console on the terminal. If you
look at Documentation/serial-console.txt in the 2.2 kernel sources,
that seems to be about what you want.

I can't foresee any reason why a terminal shouldn't do both jobs
at the same time - after all, console messages emerge from VCs
as a matter of course while you're using them for other things.
But that's a software convergence, not hardware.
