[Simh] Unix v7 tty terminals in SimH pdp11

[Johnny Billquist]

I haven't played with V7, but I assume there must either be an 
/etc/ttys, or something similar, which tells Unix on which terminal 
lines to start a login process at boot. Otherwise they are going to be 
very silent.

Also, remember to hit enter, as they will not spontaneously print out a 
prompt just because you telnet in. They have already printed a prompt 
when the login program started.
