BASIC never checks any I/O locations. No language ever checks any
I/O locations. It's the Operating System that deals with I/O
locations. Any access to I/O locations is done by asking the MOS
to do something.
 
Stop thinking about BASIC interacting with the hardware. It never
does. BASIC will function fully and correctly as long as the calls
to the entry points at &FFxx do their function.

Taxation is like dairy farming. You have to extract the maximum
amount of milk with the minimum amount of moo.
