A modem speaker is activated and deactivated based on a user modifiable schedule. The user stores schedule information in a schedule table, the schedule information describing a modem setting and a time for that setting to take effect. An automatic scheduler programs either the system clock or a clock device associated with the modem with the interrupts. When each interrupt issues, it generates a modem control command to turn the modem speaker either on or off by controlling whether or not audio signals are sent to the speaker. Alternatively, each time the modem is accessed, the automatic scheduler checks the schedule to see if audio signals should be provided to the speaker. A user may override the automatic scheduler at any time. By using the scheduler, a user can identify time periods when the modem speaker is deactivated without having to remember to turn off the speaker, and have the speaker activated during all other periods with having to remember to turn the speaker back on. |
