POKEregisterlocation,value

If the register was located in decimal location 346 and Bit 6 set the
register on or off then use this command POKE346,63. Simple. You just
don't want memory protection and all the barriers Windows provides.
Otherwise, changing data in a special file that the OS accesses would
need to be made. 

Windows blocks direct access to memory for the sake of memory
protection. 

Hey, we done accessing to a port in BASIC for MANY years on a Commodore
64. You just have to hunt the sucker or have some file that tells where
the hardware is currently located at.
