Patent number: 5202899Abstract: A computer is programmed in accordance with an algorithm which allows it to send a series of tentative unique initialization commands to a port which should be connected to a modem for the purpose of establishing what type of modem is connected if any. In accordance with an internal flag setting, an appropriate translation table is then used in any future communications with that modem to convert the basic commands used by the computer operated device to commands that will be recognized by the modem in setting up communications with other modems at the other end of a transmission line and for terminating said communications. The algorithm involved is also able to ascertain whether or not an operable modem is connected to a port by monitoring the response obtained. Thus, modems can be changed and potential technician error is eliminated due to the dynamic selection capabilities of the computer programmed to operate in accordance with the inventive concept algorithm.Type: GrantFiled: August 16, 1991Date of Patent: April 13, 1993Assignee: Rockwell International CorporationInventor: James P.
