Some are, some aren't.  The PC spec doesn't require it.

You can use the OUT and INP commands in most BASICs available for the PC
clones.  Getting the number of the port may require some research.  It's
888 (decimal) on most AT's and lesser machines. 386 boxes and up may use
other mappings (try 956 or 957).
