OUT Statement Details
 
Syntax
  OUT port, data
 
  Argument   Description
  port       The number of the port. The number must be an integer
             expression in the range 0-65,535.
  data       The data to be sent to the port. It must be an integer
             expression in the range 0-255.
 
The OUT and INP statements give a BASIC program direct control over
the hardware in a system through the I/O ports. These statements must
be used carefully because they directly manipulate the hardware.
