  • Method and apparatus for concurrent interaction with a modem having an open connection
    Patent number: 6161201
    Abstract: A method and apparatus for a connection monitor to concurrently interact with a concurrent diagnostic-capable modem during an open connection controlled by a communication application without terminating the open connection between a host system and the modem. The connection monitor and a communication application operate concurrently to enable a user to interrogate a modem for status information while a connection with the modem remains open and functional with other communication applications. A serial device driver presents two types of entry to the operating system, one for normal communications and one for a collateral or side-door entrance from a connection monitor. The serial device driver multiplexes a packaged diagnostic command into the open channel with the data process by the serial driver and dispatched to a local modem.
