Remarks
  • Windows XP and the Windows Server 2003 family of products do not use this command. It is included only to preserve compatibility with existing MS-DOS files, but it has no effect at the command line because the functionality is automatic.
  • For information about sending the value of a byte to an output port by using the o (output) subcommand, see Related Topics.
Examples
