No.  They are different interrupts.  You can shut off Ctrl-C checking
in protected mode by performing the DOS interrupt that shuts off
CTRL-C checking.  I think setting stdin to raw or binary mode will do
this automatically, but I don't remember off the top of my head.

Note that the default action for both interrupts is similar, hence the
misconception that they are the same interrupt.
