(I killed post-news just as I started to post, so I'm retrying this,
sorry if you read this twice).

In the overview section of the Library Reference manual (a handy
section to have!), on page 65:

Console and Port I/O

I'm sure these routines use the BIOS calls to talk to the port.
If you want anything faster, use the pointers mentioned by someone
else... But if you have an older CGA (or other type of display) then
watch out for a flakey screen with direct access to the memory.

Also, poking to memory won't move the cursor...
