Abstract
The present invention discloses a method and apparatus to process a Caller-ID signal and store the caller-ID message in a buffer while the computer system is in a sleep state. The telephone controller detects the telephone ring and switches the signal path to receive the Caller-ID signal. A Caller-ID decoder converts the received Caller-ID signal into a Caller-ID code to be stored in a Caller-ID buffer. The processor sends a signal to activate the computer system. Upon activation, the computer system retrieves the Caller-ID code from the Caller-ID buffer. Therefore, the Caller-ID code is not lost during the powered-down or sleep period.
