These commands enable command line and script access directly to I/O ports on PC hardware.

The inb, inw and inl commands perform an input (read) operation on the given I/O port, and print the result.

The size of the operation is selected according to the suffix, with b meaning byte, w meaning word (16 bits) and l meaning long (32 bits).
