No it's not. It's located in IO address 379h, which can be referenced
by an IN or OUT machine instruction. If you use Ada under MSDOS this is
trivial, but current versions of Windows block direct access to IO ports
so you'll have to call some kind of driver software. Windows is not
designed for low level programming.
