As for simh; I suggest another escape character, which gives a restricted

Oh no please. When running the simh console inside a screen session accessed 
via an ssh connection running in a whatever terminal emulation started on a 
whoknows system the probability of having your escape character being 
masked/used/nullified by one of the layers is probably near to 1. Specially if 
your keyboard is not the US variant.

I can't escape into klh10 without a lot of keyboard black magic... for example.

I vote for a separated telnet port for the "hardware console" connection.
It's not that bad.  Certainly not probability 1.

We already have to deal with ^P for the VAX rom code & the simulator escape (^E).

Set running-escape <key specifier> if the chosen default is a problem.

Or, overload ^E - if the simulation is running, you get the restricted command line with the simulation running. To stop the simulation, you then type 'stop' to the restricted command line, which gets you the current (full) simh command line . I actually like this better, except for the finger retraining that's required for users.

There's no need to require (and secure) another telenet port for this. Networking is optional in simh. And what I suggested fits reasonably easily into the basic simh model.

I was going to mention the security issues with using telnet for anything - but I've caused enough trouble.

This communication may not represent my employer's views,
if any, on the matters discussed.
