The AAA is natively supported by ITS.

Add new option, say -r or -R. Used to re-run the subprocess if it exits.
Intended use case: <terminal> -r telnet host
so that if host goes down, the terminal will reconnect when host comes back up.
Real photo vs emulator.

Most terminals supported have no arrows keys, and most emulators have them unmapped. I suggest it would be useful to map them to Emacs cursor movement, or similar depending on the intended target system. I.e. Datamedia could use E cursor movement.
Datapoint 3300 documentation says codes 136 and 137 are arrows.
The terminal emulator for the vt05, vt52, dp3300, dm2500 and gecon may fail to build on MacOS with libsdl2
. This was discovered building ITS using the pdp10-kl emulator. MacOS was 11.6.4, libsdl2 version 2.0.20 installed by MacPorts and clang13.
The error was
cc -Wall -Wno-unused-parameter -Wno-parentheses -Wno-unused-result -O3 -o vt05 vt05.c terminal.c `sdl2-config --libs --cflags` -lm -lpthread

make: *** [vt05] Error 1
The cause of the error seems to be fragile conditionalization in the SDL.h
header file. The error can be fixed my moving
the include of SDL.h
to the top of the includes (for example, here in vt05.c):
#define _XOPEN_SOURCE 600
#define _DEFAULT_SOURCE
#include <SDL.h>
#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
#include <stdarg.h>
#include <ctype.h>
Making this change in all of the source files allow the build to complete successfully.
The fragile conditionalization in SDL.h
seems to be a known problem and the recommended solution is to include SDL.h
as early as possible.
