Overview
| Comment: | Clarified that SCREEN_MANAGER=none is for interactive use only in the README.md file, and made a test for this high up in the pidp8i script. |

| 23:41 | Merged in trunk changes, leaving only the dtach changes in this branch. Leaf check-in: 16b4f0c7e2 user: tangent tags: screen-mgr-none-dtach | |
| 23:23 | Cherry-picked the elements of branch screen-mgr-none-dtach that don't involve dtach, the only part of that branch that doesn't currently work. The main user-visible feature of this is the "none" option. check-in: 9d08417d8e user: tangent tags: trunk | |

| 18:37 | Moved the dtach socket from /tmp to $prefix/run. systemd does strange things with /tmp, and systemd likes "run" for files like this. check-in: d80f67fef7 user: tangent tags: screen-mgr-none-dtach | |

this option.
Unlike `screen` and `tmux`, there is no command layer enetered
via an "attention" keystroke in `dtach`. The only key that `dtach`
scans for from the terminal is the detach keystroke, which we leave
at its default, <kbd>Ctrl-\\<kbd>.
* **<tt>none</tt>**: Effectively aliases the `pidp8i` and `pidp8i start`
commands, attaching the simulator to the local console. The `pidp8i
stop` command becomes a no-op, since stopping the simulator is then
done in the standard SIMH way: <kbd>Ctrl-E, quit</kbd>.
Note that the alternative screen managers are not installed by default.
If you set `SCREEN_MANAGER=tmux`, you must then ensure that `tmux` is in
fact installed before the `pidp8i` script goes to try and use it. On
Raspbian, this is done by:
$ sudo apt install tmux

* **<tt>none</tt>**: This mode is for interactive use, allowing you to
run the installed simulator with the installed media without any
screen manager at all.
In this mode, the `pidp8i` and `pidp8i start` commands do the
same thing: run the simulator directly attached to your current
interactive terminal. The `pidp8i stop` command becomes a no-op,
since stopping the simulator is then done in the standard SIMH way:
<kbd>Ctrl-E, quit</kbd>.
Note that the alternative screen managers are not installed by default.
