<h1><a name="kap_interrupt_0110"></a>INT 10,3 - Read Cursor
Position and Size</h1>
<p> AH = 03</p>
<p> BH = video page</p>
<p> on return:</p>
<p> CH = cursor starting scan line (low order 5 bits)</p>
<p> CL = cursor ending scan line (low order 5 bits)</p>
<p> DH = row</p>
<p> DL = column</p>
<p> - returns data from ~BIOS DATA AREA~ locations 40:50, 40:60
and 40:61</p>
<p> - the ~6845~ can also be used to read the cursor position</p>
<p> - the return data can be circumvented by direct port I/O to
the 6845</p>
<p> CRT Controller since this function returns the data found in
the</p>
<p> BIOS Data Area without actually checking the controller</p>
