Apparatus and method for indicating connection state of input/output cable |
摘要 |
An apparatus and method for indicating the connection state of an input/output cable between an ATAPI drive and a host. The apparatus includes an indicator and a controller. The indicator is a communication device between an AT Attachment Packet Interface (ATAPI) drive and a host interconnected via the input/output cable and indicates in response to a control signal whether the AT Attachment Packet Interface (ATAPI) drive is connected to or disconnected from the host via the input/output cable. The controller sets a flag to check the connection state of the input/output cable, when power is applied to the AT Attachment Packet Interface (ATAPI) drive, and outputs the control signal to the indicator to indicate that the input/output cable is not connected to the host when a command is not received from the host for a predetermined period of time.
