[Simh] SIMH console settings for escape sequence support

[Paul Koning]

I've noticed that terminal handling on the SIMH console with RSTS/E was never quite right; it would not do "set terminal/inquire" and editing keys that produce escape sequences would be mangled.

This turns out to be due to the "printable control characters" configuration setting.  Its default value does not include ESC as a printable character, so it gets discarded rather than sent to the terminal window.

To fix this, use the following SIMH command:

set console pchar=01000023600

With that setting, escape sequences work properly on the console.  Something similar probably applies to other operating systems and processor types, if they use escape sequences on the console terminal.  The pchar value is octal on PDP11 and other machines that are conventionally octal; it's hex on VAX and other hex machines, so adjust the "set" command accordingly.
