Re: [LINUX5250] Keyboard States

[MarkB@xxxxxxxxxx]

This thread started when you mentioned you wanted to imporve the
functionality of distinguishing between various stated.
You also specifically mentioned the Pre Help Error State in your post.

I should have been more explicit in that the behavior I was describing was
specifically how to handle the help key in Pre Help Error State (which as
far as I knew was not working last time I checked. All appologies if I am
mistaken.)

When the keyboard is in Pre Help Error and the user presses the HELP it is
incorrect to send the HELP AID key (as far as I understand from the
documentation, behavior of client access, and packet captures) .
What is correct is what I mentioned. Construct a new display data stream as
described, and send that to the 400.
In turn, it will bring up a screen giving you more verbose error
information.

For example, if the error is "Cursor in protected area of display."

Then the "Additional Message Information" is:
 Message ID . . . . . . :   KBD0005       Severity . . . . . . . :   10
 Message type . . . . . :
 Message . . . . :   Cursor in protected area of display.
 Cause . . . . . :   To enter data, the cursor must be in an input field on
the
   display.  Data cannot be entered in a protected area of display.
 Recovery  . . . :   Press Error Reset key.  Move the cursor to a field
where
   the data can be entered and then enter the data.

It was just one little piece to add to the overall puzzle of various states
and actions.

If you need more specific information please contact me via email.

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.
