Abstract
A method and system checking a state of a peripheral without help of a special I/O module regardless of port types between the peripheral and a state-requiring device can be achieved by adding state information representing at least one detailed state of the peripheral to an identification region of the peripheral having identification information identifying the peripheral, and transferring the identification region with the state information to the state-requiring device. The state of the peripheral is analyzed using the state information extracted from the identification region received by the state-requiring device.
Claims13
A method of checking a state of a peripheral having identification information representing identity of the peripheral, the method comprising:
- adding state information representing at least one detailed state of the peripheral to an identification region having the identification information and transferring the identification region with the state information;
- and
- receiving the transferred identification region with the state information and analyzing the state of the peripheral using the state information extracted from the received identification region.
An apparatus checking a state of a peripheral having identification information representing identity of the peripheral, the apparatus comprising:
- a programmed computer processor as a state analyzer receiving an identification region with added state information representing at least one detailed state of the peripheral from the peripheral, extracting the state information from the received identification region, analyzing the state of the peripheral using the extracted state information, and outputting an analyzed result.
A peripheral, comprising:
- a transfer determiner determining whether there is a need to transfer a state of the peripheral and outputting a result of the determination as a control signal;
- a state checker checking the state of the peripheral in response to the control signal and outputting state data representing the checked state of the peripheral;
- a pattern converter converting a pattern of the state data into a pattern of identification information of the peripheral and outputting the pattern-converted state data as state information of the peripheral;
- an information adder adding the state information to an identification region of the peripheral containing the identification information and outputting the identification region with the added state information;
- and
- a transferor transferring the identification region with the state information.
