Does anyone know how to set the cursor
character on an IBM PC? I'd like to
get rid of the silly little blinking underline.
OK, I know, RTFM right. Well I read all the manuals
I've got, and I can't find any reference whatsoever.
With my luck, they probably have a dedicated ROM
to force you to use the foolish default.

My Tech Ref Manual listing of the ROM BIOS shows that you can change the
cursor shape (and perhaps remove it altogether) with a call of INT 10H.
Set AH to 1. CH needs to be the start line for the cursor in bits 0-4,
being careful to zero bits 5 and 6. CL bits 0-4 are the end line for the
cursor. What I mean by 'line' is the scan line, not the character line.
The number of scan lines depends on the display adaptor; it's around 8
for the color graphics adaptor and 14 for the mono adaptor. I am told
you can even have a split cursor by making the start line > the end
line.
I have tried this on my cheap PC compatible and it even seems to work
there. Hope this is of help,
