From: Haijun Liu <haijun.liu@xxxxxxxxxxxx> Control Port implements driver control messages such as modem-host handshaking, controls port enumeration, and handles exception messages. The handshaking process between the driver and the modem happens during the init sequence. The process involves the exchange of a list of supported runtime features to make sure that modem and host are ready to provide proper feature lists including port enumeration. Further features can be enabled and controlled in this handshaking process.
