KMC/DUP are used for the 2780 emulation feature, which is a rather obscure
layered product -- I don't know anything about it.
As of RSTS V9.0, if memory serves, terminal configuration is no longer set
during Sysgen. Instead, the monitor contains drivers for each supported
terminal interface, and these are loaded at startup according to what hardware
was found.
When you boot the system (at the "Start timesharing" prompt) enter "hardware
list" to confirm that the DZ11s were indeed seen:

Next... I don't know why you expected telnet ports 10001-10007 to be active
when you attached 10001. The attach command sets up just that TCP port number
as one SIMH listens to, serving all the mux ports behind it. So you should be
able to telnet to the port you specified multiple times, and when you do, SIMH
should tell you that you're now connected to some port:
pkoning$ telnet localhost 9999
Trying ::1...
Connected to localhost.
Escape character is '^]'.
Connected to the PDP-11 simulator DZ device, line 1

The other point to remember is that RSTS expects to do auto baud on all ports
other than 0, in the standard setup at least. So you need to enter RETURN
twice before you get the login prompt.
