ports - use <pc.h>'s in* and out* calls
interrupts - wait for 1.11, but there's only a few you can rely on.
segments - there aren't any (effectively).  1.11 adds some functions to
  deal with "selectors", but nothing in this realm is compatible with
  turbo-c.

I don't think it knows about baud rates.  I use a separate utility to
program the baud rate to 19200.  Note that you may not be able to
handle the interrupts that quickly from protected mode.
