Sleep Mode Entry. The modem enters the low power sleep mode when no line
connection exists and no host activity occurs for the period of time specified in the S24
register. All modem circuits are turned off except the internal clock circuitry in order to
consume reduced power while being able to immediately wake up and resume normal
operation.
Wake-up. Wake-up occurs when a ring is detected on the telephone line, the host writes
to the modem (parallel interface), or the DTE sends a character to the modem (serial
interface).
