<p>A method for transmitting commands from an originating program to a receiving program uses the data area (26) of instructions. A first set of commands are predefined for use in the command area (24) of the instructions. A second set of commands, excluded from the first set of commands, can pass through operating system modules (18), including driver software (16), by inserting them in the data area (26) of an instruction. The second set of commands are identified by including identification codes in the data area (26), such as a predefined random number key. In addition, the command area (24) can be used to eliminate the majority of normal commands quickly by always using a specific address and command in the first set of commands to transmit the second set of commands.</p> |
