Abstract:
A method for a connection monitor to interact with a concurrent diagnostic-capable modem during an open connection controlled by a communication application without terminating said open connection of said concurrent diagnostic-capable modem, said method comprising the steps of:a) selecting a serial device driver having both a serial driver and an inband diagnostic driver from among at least one other device driver when said concurrent diagnostic-capable modem is interfaced with said communication application;b) generating a diagnostic command as determined by said connection monitor;c) issuing a diagnostic API call comprised of said diagnostic command to said serial device driver having both a serial driver and an inband diagnostic driver;d) extracting at said inband diagnostic driver said diagnostic command from said diagnostic API;e) multiplexing at said serial device driver said diagnostic command and data passing through said serial driver into said open connection;f) demultiplexing at said modem said diagnostic command to a diagnostic process and said data to a traditional communication process; andg) processing said diagnostic command at said concurrent diagnostic-capable modem as directed by said connection monitor.
