You may have to learn some. Or at least be able to read it.
And I have to ask. The hardware has changed a lot since the days of
DoS, and things that worked then may cause strange results on modern
hardware. Do you know modern hardware, or are you still using dos-era
hardware?

I believe this should be $0x4, as you want to *set* the values, not
get them.
You also need to open the file "/dev/io". I believe that leaving this
file open for anything more than a handful of instructions would be a
bad thing, but I'm not going to verify it.
Best of luck,
