Overview
| Comment: | Removed -E mode from the dtach call in the pidp8i script: we *want* to be able to detach from the terminal. This should not interfere with terminal escapes from the simulator since dtach should be scanning for this only from the terminal *input* side. If someone comes up with a reason that SIMH or the simulated software needs Ctrl-\ for its own purposes, we can change the detach character to something else. |

us have it both ways.
The `SCREEN_MANAGER` setting is for use by those that need something
other than GNU `screen`. There are several alternatives:
* **`screen`**: The default, per above.
* [**`tmux`**][tmux]: A popular alternative to `screen`, especially
on BSD platforms. Note that the "attention" character for `tmux`
is <kbd>Ctrl-B</kbd> by default, not <kbd>Ctrl-A</kbd> as with
`screen`.
* [**`dtach`**][dtach]: A minimalist alternative to `screen` which
provides only its terminal attach/detach features.
In addition to the virtues called out on the program’s home page,
use of this option has a side benefit for some PiDP-8/I users:
`screen` and `tmux` assume an [ANSI X3.64 terminal][ansit] (e.g. DEC
VT102 or xterm), because they interpret escape codes to provide
features such as their scrollback buffer. It is uncommon to find
PDP-8 software that uses ANSI terminal escape codes since almost all
PDP-8 computers sold predate that standard. Most PDP-8 software
assumes a dumb teletypewriter, and of the software that does make
use of a smart terminal, there’s a good chance it wants something
else, such as a [Tek 4010][t4010] series terminal. These ANSI screen
managers can therefore get in the way and mess things up.
`dtach` doesn’t interfere with terminal escape code handling; thus
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.
