[comp.sys.ibm.pc.misc] Question about removing text cursor

	Dear Netters,

I have a question about turning the cursor on and off in text
modes. According to the interrupt documentation, the interrupt 0x10
called with ax=0x100 and cx=0x2000 should turn the cursor off. That
works nicely. The problem is to turn it on again. Setting the cursor
shape, using the same interrupt with cx=0xE0F works on some systems,
while it does not on others. All the computers I have tested, which
use EGA boards seem to have this problem. The only way to get the
cursor back is to reboot the system. :-(
Any ideas?
						Udo
