Fred, as per the manual, you actually do program the cursor "style" through something like hyperterminal (what I used). This is retained in the eprom chip on the board that you built. You can also make your own boot up text as well. This thing is really pretty nifty, thanks for turning me on to it

Now I just have to figure out why it's not happy with my machine PC.
Set cursor style: -
?c[style] - [style] is range from 0-3.
- A 0 configures are no cursor, a 2 as a non blinking cursor and a 1 or 3 as a blinking cursor.
Hope this helps you.
