Re: [LINUX5250] Keyboard States

Mark,

I was asking where I would find the "little blinking numbers" and
how to tell which one to put in the corner, not how to send the help
sequence.   None of the documentation you referenced explained this.

At any rate, I've already done a "best guess scenario" with the help
from Buck Calabro, and put it into CVS.

I decided to forego having those numbers blink in the corner, and simply
display the human-readable error message immediately.
