The best way to see where the '-P' switch takes effect is to examine the
patch itself. It clearly shows:

+ if (protected)
+ d->read_audio = scsi_read_D8;

for scsi_interface.c (try to find that exact row from patched version).
d->read_audio is a function pointer which can be assigned to any of those
read commands. The '-P' switch forces it to be scsi_read_D8, but you may
alter it to some other read command.

Remember (a) that the patch is not written by me but instead a clever
Finnish hacker who sent the patch to me, (b) that following my suggestion
about various read commands might be DANGEROUS and I give ABSOLUTELY NO
WARRANTY of what happens. It is known that some CD-RW drives MIGHT BE
DAMAGED BECAUSE OF CORRUPTION OF FIRMWARE with some random commands.
