Abstract

Typically, modem initialization strings are set based on the user entering the type of modem in an input panel. The invention described herein involves a method of first probing to determine what type of machine the modem is attached to, followed by possibly probing the modem to determine what type of modem it is.

Automated Creation of Modem Initialization String For Call Home On A Storage Device

Typically, modem initialization strings are set based on the user entering the type of modem in an input panel. In more complex systems, replacing a modem, or changing the configuration of the modem attachment requires changing many settings manually. It would be useful to have a methodology that would automatically configure the modem initialization string based on probing the modem, its connection type, and the type of machine the modem is connected to. US Patent #5,926,506 references a way to probe a modem, and configure the modem and port of the machine based on the response from the modem, but it does not account for what type of machine the modem is connected to, which can cause a great deal of variability in the modem's initialization string.

The invention described herein involves a method of first probing to determine what type of machine the modem is attached to, followed by possibly probing the modem to determine what type of modem it is. These two pieces of information provide a means to selecting which modem initialization string is correct.

First, the machine is probed to determine what type of machine it is. Depending on the type, a serial switch may be required, in which case the modem initialization string is known. If the machine type is such that either a switch or direct attachment of a modem is allowed, then the piece of hardware attached to the serial port of...
