I was trying to start ADVENT again on my PDP-8, this time all with my
Teleray 3511D terminal for a change (often I use minicom). I found that I
could not escape to start the program. Instead, a '[' is printed, which is
character code 133 octal. Escape is 033 octal. On minicom, things work just
fine hitting the escape key on my keyboard.
Is my terminal acting up? Is ALTMODE not defined as 033 on this terminal?
Something else?
If it's not acting up, any ideas how I can send a 033 from the terminal?
Thanks,
Kyle

In ASCII-1963, ESC was octal 176. I'm not sure there was a standard for
ALTMODE, but it's generated several different things on Teletypes,
including octal 175 and 176. I wouldn't be surprised if Teleray copied
Teletype.
I haven't ever heard of ALTMODE sending 133. Possibly the terminal is
sending something other than 133, but the software is echoing it as '['.
Try control-shift-K, or if there is a '[' on the keyboard, control-[.

I believe they copied Teletype; the keyboard layout is identical to the
Model 33 ASR for one. I haven't yet determined the code yet. Have a few
other things I need to get done tonight. Distractions!

Yes, I think you're right. Probably just a coincidence that it's one bit
off from modern ESC.
Try control-shift-K, or if there is a '[' on the keyboard, control-[.
