Hiya,
    I got to thinking this morning of a feature of Speakup which, I admit, I've been sort of taking for granted lately.  It's the attribute reading key--speakup+keypad period.
    What I'm wondering about is how, exactly, Speakup gets information on the colors of the console, or of certain text therein?
    This is an issue which seems on the whole to be fairly complicated under a Windows system: I've yet to really find a screen reader which will duplicate it.  I'm wondering, then, how Speakup does it?
Thanks much for indulging me,
Zack.

JFW has always done this, and I would guess that WE does too.
I think Jaws for Dos did too.

Using the standard text console there are two bytes of information
stored in video memory for each screen position.  One for the
character stored and one for the colour and attribute.  The
colour/attribute consists of background colour and forground colour
with a couple of bits dedicated to blinking or high intensity and the
like.  So basically you mask off the info and then use that to point
in to an array to get the text string for the colours you want to
say.  You do the same thing with the characters to get the
pronunciation.

Howdy,
    This is very enlightening.  Gives me a bit of a glimpse at how things 
like this are handled.  I'm quite pleased with Speakup's performance, truth 
be told.Thanks much,
Zack.
