Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

     The Port Input (I) command reads and displays a byte from a
     specified hardware port. The specified port can be any 16-bit
     address.
 
     This command is often used in conjunction with the Port Output (O)
     command. Use this command to write hardware-specific programs in
     Assembly mode.
 
     See: ◄Port Output (O) Command-Window Command►
 
     NOTE: This command may affect the status of the hardware using
           the port.
