Exception handler for PII

Hi,
I am writing a code for the software instruction breakpoints. I want to
set the RF flags in EFLAGS register in the exception handler.
Below is my code. But somehow looks like the flag was not getting
set.(because the excp handler gets called continously)
Can anyone see programming defect here..

pushl eax
movl eax, 4*4(esp)
orl eax,$0x00010000
movl 4*4(esp),eax
popl eax
iret

In the above code, my exception handler gets called without change in the
privilege level.



Info: Because the debug exception for an instruction breakpoint is
generated before the instruction is
executed, if the instruction breakpoint is not removed by the exception
handler, the processor

will detect the instruction breakpoint again when the instruction is
restarted and generate another

debug exception. To prevent looping on an instruction breakpoint, the Intel
Architecture

provides the RF flag (resume flag) in the EFLAGS register When the RF flag
is set, the processor

ignores instruction breakpoints.
