   outp, outpw

   Usage

   #include <dos.h>
   void outp(int port_address,int value);
   void outpw(int port_address,int value);

   Description
   outp  and outpw are C interfaces to the 8086 hardware I/O ports  using
   the "out" 8086 instructions.

   outp writes the least significant byte of value to the specified port.
   outpw writes the word value to the specified port.
   If dos.h is included, the compiler generates inline code for outp  and
   outpw.
