  • Modem apparatus and method for serial command and data multiplexing
    Patent number: 6260084
    Abstract: A modem and associated method with both an RS-232 interface and a USB interface connects to a host. The modem detects which of the two interfaces is connected to the host and determines an appropriate data path. For connections to the USB interface, data is routed through a USB processor and over a serial link to the modem processor responsible for modem communications and the transfer of modem data to the POTS. The serial link between the USB processor and the modem processor is used to transfer both modem data and processor communications. A plurality of control lines are used to indicate the type of data being transferred over the serial link. For RS-232 connections, the modem data is transferred to the modem processor. Thus, one modem device may be used for either USB or RS-232 connections.
