Hi,

Original question:
Someone asked me why pressing Ctrl/p in vi caused a 8200 to halt.
Is there any way to use Ctrl/p safely?

Many thanks to

Here's Tom Webster's summary-like answer:
> Ctrl-P should only halt the system if the follwoing two conditions are
> met:
>
> 1. The user is on a hardwired console.
>
> 2. The system key is in "enable" mode.
>
> If you keep users off of the head, you won't have any trouble. If you

>
> As a general rule, keep the sys key in "secure" mode unless you are doing
> maint or something else where you need to be able to halt the system in
> a hurry.

And Bill Carlson's answer:
> FYI when you get the the prompt >>> type c (continue)

Paul A Sand's answer:
> On our old DEC 4000, this is controlled by the monitor-level
